Simplifying algebraic expressions is not just an abstract mathematical exercise; it has practical applications in various fields, including physics, engineering, and computer science. For instance, in physics, simplifying equations can help in calculating trajectories or electrical circuits more efficiently. In engineering, simplified expressions can make designs more cost-effective and easier to implement. Even in computer science, simplified algorithms can run faster and consume less memory. The ability to simplify expressions is therefore a valuable asset in any technical field. Simplification not only makes expressions more concise but also reveals underlying patterns and relationships that might not be immediately apparent in their original form. This process enhances both your problem-solving skills and your understanding of mathematical concepts. The goal is to transform the expression into its most understandable and manageable state, making it easier to work with in further calculations or analysis. Keep this in mind as we delve into the specifics of simplifying the expression ${\frac{26ac^2}{13a}}$.

Moreover, the methods used in simplifying algebraic expressions extend beyond pure mathematics. They foster analytical thinking and attention to detail, skills that are crucial in many aspects of life. When you simplify an expression, you are essentially breaking it down into its components, identifying common factors, and reorganizing it in a more logical way. This process mirrors how we approach problem-solving in general: by dissecting complex issues into smaller, more manageable parts. By understanding the logic behind simplification, you will be better equipped to tackle various challenges, whether in academics, professional settings, or everyday situations.

Step-by-Step Simplification of ${\frac{26ac^2}{13a}}$

Let's break down the process of simplifying the expression ${\frac{26ac^2}{13a}}$ into easy-to-follow steps. This will provide a clear understanding of the techniques involved and build your confidence in handling similar problems. The core idea behind simplifying this expression is to identify common factors in the numerator and the denominator and then cancel them out. This method relies on the principle that dividing both the numerator and the denominator by the same non-zero factor does not change the value of the expression. By systematically removing these common factors, we can reduce the expression to its simplest form.

Step 1: Identify Common Factors The first step in simplifying the expression ${\frac{26ac^2}{13a}}$ is to identify the common factors in the numerator and the denominator. Here, the numerator is ${26ac^2}$ and the denominator is ${13a}$. We can break down the numbers and variables into their prime factors to make the common factors more apparent. The number 26 can be factored as ${2 imes 13}$, and the term ${ac^2}$ consists of the variables ${a}$ and ${c^2}$. The denominator, ${13a}$, is already in a relatively simple form. Looking at both the numerator and the denominator, we can immediately see that 13 and ${a}$ are common factors. Identifying these common factors is crucial because it sets the stage for the next step, which involves canceling them out. The ability to recognize these shared elements quickly will significantly speed up the simplification process. This step highlights the importance of having a solid understanding of factors and multiples, which is a fundamental concept in mathematics.

Step 2: Cancel Common Factors Once we have identified the common factors in the expression ${\frac{26ac^2}{13a}}$, the next step is to cancel them out. In this case, the common factors are 13 and ${a}$. We can rewrite the expression to explicitly show these factors:

{rac{26ac^2}{13a} = rac{2 imes 13 imes a imes c^2}{13 imes a}}

Now, we can cancel the common factor of 13 from both the numerator and the denominator:

{rac{2 imes \cancel{13} imes a imes c^2}{\cancel{13} imes a} = rac{2 imes a imes c^2}{a}}

Next, we cancel the common factor of ${a}$ from both the numerator and the denominator:

{rac{2 imes \cancel{a} imes c^2}{\cancel{a}} = 2c^2}

By canceling these common factors, we effectively simplify the expression. This process is based on the principle that dividing both the numerator and the denominator by the same non-zero quantity does not change the value of the fraction. This cancellation step is a powerful technique that allows us to reduce complex expressions to their simplest forms. It is essential to ensure that the factors being canceled are indeed common to both the numerator and the denominator to maintain the integrity of the expression.

Step 3: Write the Simplified Expression After canceling the common factors in the expression ${\frac{26ac^2}{13a}}$, we arrive at the simplified form. From the previous step, we have:

{rac{2 imes \cancel{a} imes c^2}{\cancel{a}} = 2c^2}

Thus, the simplified expression is ${2c^2}$. This is the simplest form of the original expression, and it contains no common factors between the numerator and the denominator. Writing the simplified expression is the final step in this process, and it represents the result of all our efforts. The simplified form ${2c^2}$ is much easier to work with than the original expression, making it simpler to use in further calculations or analyses. This step demonstrates the power of simplification in making mathematical expressions more manageable and understandable. It also underscores the importance of correctly identifying and canceling common factors to arrive at the correct simplified form. The ability to simplify expressions to their most basic form is a cornerstone of mathematical proficiency.

Common Mistakes to Avoid

When simplifying algebraic expressions, it's easy to make mistakes if you're not careful. Here are some common errors to watch out for and how to avoid them:

1. Incorrectly Identifying Common Factors: One of the most frequent mistakes is failing to accurately identify the common factors in the numerator and the denominator. For example, in the expression ${\frac{26ac^2}{13a}}$, if you overlook the factor of 13 or ${a}$, you won't be able to simplify the expression correctly. To avoid this, always break down the numbers and variables into their prime factors. This makes it easier to see all the common elements. Additionally, double-check your work to ensure that you haven't missed any factors. Precision in this step is crucial for the overall simplification process.

2. Canceling Terms Instead of Factors: A critical mistake is canceling terms (separated by addition or subtraction) instead of factors (separated by multiplication). For instance, in an expression like ${\frac{26 + ac^2}{13 + a}}$, you cannot simply cancel the 26 with the 13 or the ${a}$ terms. Cancellation is only valid for factors. To prevent this error, remember that cancellation is essentially division, and it only applies to common multipliers. If there are addition or subtraction operations, you must simplify those separately before attempting any cancellations. This distinction between terms and factors is a fundamental concept in algebra, and understanding it is vital for avoiding mistakes.

3. Forgetting to Simplify Completely: Sometimes, after canceling some common factors, there may still be other factors that can be simplified. Failing to simplify the expression completely is another common mistake. In the expression ${\frac{26ac^2}{13a}}$, if you only cancel the 13, you would be left with ${\frac{2ac^2}{a}}$, which can be further simplified by canceling the ${a}$. To avoid this, always double-check your simplified expression to ensure there are no more common factors. Simplify the expression in stages if necessary, making sure each step is correct before moving on to the next. Completing the simplification ensures that you have reached the most concise form of the expression.

4. Sign Errors: Sign errors can easily occur, especially when dealing with negative numbers or expressions. For example, if there is a negative sign in the numerator or the denominator, it’s important to carry it through correctly during the simplification process. Overlooking a negative sign can lead to an incorrect final result. To minimize sign errors, it is a good practice to handle the signs separately from the numbers and variables. Keep track of the negative signs carefully and ensure they are applied correctly after each step. This methodical approach will help maintain accuracy throughout the simplification process.

5. Misunderstanding Exponent Rules: When simplifying expressions with exponents, it's crucial to apply the exponent rules correctly. A common mistake is to add exponents when you should multiply them, or vice versa. For instance, when simplifying terms like ${c^2}$, ensure you understand that it means ${c \times c}$ and that it cannot be further simplified unless there is a common factor in the denominator. To avoid these errors, review the basic exponent rules regularly and practice applying them in various simplification problems. Understanding these rules thoroughly will prevent mistakes and ensure that you simplify expressions involving exponents accurately.

By being aware of these common mistakes and taking steps to avoid them, you can improve your accuracy and confidence in simplifying algebraic expressions. Careful attention to detail, a solid understanding of the basic principles, and consistent practice are key to mastering this essential skill.

Solution:

1. Identify Common Factors: The numerator is ${24a^2b^3}$ and the denominator is ${8ab^2}$. Break down the terms:
   • ${24 = 3 \times 8}$
   • ${a^2 = a \times a}$
   • ${b^3 = b \times b \times b}$

So, the expression becomes ${\frac{3 \times 8 \times a \times a \times b \times b \times b}{8 \times a \times b \times b}}$. The common factors are 8, ${a}$, and ${b^2}$ (which is ${b \times b}$).

   • ${36 = 4 \times 9}$
   • ${p^4 = p \times p \times p \times p}$
   • ${q^2 = q \times q}$

So, the expression becomes ${\frac{4 \times 9 \times p \times p \times p \times p \times q \times q}{9 \times p \times p \times q}}$. The common factors are 9, ${p^2}$ (which is ${p \times p}$), and ${q}$.

2. Cancel Common Factors: Cancel the common factors from the numerator and the denominator:

{rac{4 \times \cancel{9} \times \cancel{p} \times \cancel{p} \times p \times p \times \cancel{q} \times q}{\cancel{9} \times \cancel{p} \times \cancel{p} \times \cancel{q}} = 4p^2q}
