Example

$( \frac{x}{6} {)^2}$

#### Step 1: Understand the Power of a Quotient Rule

The Power of a Quotient Rule states that when you have a fraction raised to an exponent, both the numerator and the denominator are raised to that exponent. In mathematical terms, this can be expressed as: $\left( \frac{a}{b} \right)^n = \frac{a^n}{b^n}$ In this problem, we have the fraction $\frac{x}{6}$ raised to the power of 2. According to the Power of a Quotient Rule, we will need to raise both the numerator $x$ and the denominator 6 to the power of 2.

#### Step 2: Apply the Exponent to the Numerator

First, let's focus on the numerator of the fraction, which is $x$. When we raise $x$ to the power of 2, we get: $x^2$ This is straightforward because any variable raised to an exponent is simply that variable multiplied by itself the number of times indicated by the exponent. In this case, $x$ is multiplied by itself once, resulting in $x^2$.

#### Step 3: Apply the Exponent to the Denominator

Next, we need to apply the exponent to the denominator of the fraction, which is 6. When we raise 6 to the power of 2, we get: $6^2 = 6 \times 6 = 36$ This is also straightforward because raising a number to an exponent means multiplying that number by itself the number of times indicated by the exponent. In this case, 6 is multiplied by itself once, resulting in 36.

#### Step 4: Combine the Results

Now that we have raised both the numerator and the denominator to the power of 2, we can combine these results to form our simplified fraction. The numerator is $x^2$ and the denominator is 36, so the fraction becomes: $\frac{x^2}{36}$ This is the simplified form of the original expression $\left( \frac{x}{6} \right)^2$.

#### Step 5: Verify the Solution

To ensure that our solution is correct, we can verify it by considering the original problem and the steps we took to simplify it. We started with the fraction $\frac{x}{6}$ raised to the power of 2. By applying the Power of a Quotient Rule, we raised both the numerator and the denominator to the power of 2, resulting in $x^2$ and 36, respectively. Combining these results gave us the simplified fraction $\frac{x^2}{36}$. This confirms that our solution is accurate and follows the rules of exponents.

FAQs

Here are some frequently asked questions about the power of a quotient rule:

#### 1. What is the power of a quotient rule?

The power of a quotient rule states that when raising a fraction to a power, you can separately raise the numerator and denominator to that power. Mathematically, it is expressed as: (a/b)^n = (a^n) / (b^n), where 'a' is the numerator, 'b' is the denominator, and 'n' is the exponent.

#### 2. How do you apply the power of a quotient rule?

To apply the rule, follow these steps: 1) Identify the fraction and the exponent. 2) Raise both the numerator and denominator to the power of the exponent. 3) Simplify the resulting expression if possible. For example, (x/y)^3 = (x^3) / (y^3).

#### 3. What is an example of the power of a quotient property?

A simple example is: (2/3)^4 = (2^4) / (3^4) = 16 / 81. This demonstrates how the exponent is applied to both the numerator and denominator separately.

#### 4. How does the power of a quotient rule relate to other exponent rules?

The power of a quotient rule is closely related to other exponent rules, such as the product rule and the power of a power rule. It complements these rules in simplifying complex expressions involving fractions and exponents.

#### 5. Can the power of a quotient rule be used with negative or fractional exponents?

Yes, the rule applies to any real number exponent, including negative and fractional exponents. For negative exponents, remember to flip the fraction and change the sign of the exponent. For fractional exponents, apply the rule as usual, but be careful when simplifying roots.

Prerequisites

Understanding the power of a quotient rule is crucial in advanced algebra, but it's essential to have a solid foundation in several prerequisite topics. One of the fundamental concepts you'll need to grasp is the negative exponent rule. This rule is vital when dealing with negative exponents simplification, which often occurs in quotient expressions.

Another key prerequisite is simplifying rational expressions and restrictions. This skill is indispensable when working with the power of a quotient rule, as it involves simplifying expressions with exponents. Being proficient in this area will make manipulating complex quotient expressions much more manageable.

Additionally, mastering the art of adding and subtracting rational expressions is crucial. This knowledge forms the basis for more advanced operations with rational expressions, which are at the heart of the power of a quotient rule.

While it might not seem immediately relevant, understanding continuous growth and decay can provide valuable context for applying the power of a quotient rule in real-world scenarios. This topic, which includes the continuous compound interest formula, demonstrates practical applications of exponents in quotients.

Interestingly, even geometric concepts like similar triangles can play a role in understanding the power of a quotient rule. The concept of similar triangles ratios can help visualize proportional relationships, which is beneficial when working with quotients raised to powers.

Lastly, being comfortable with solving polynomials with unknown constant terms is essential. This skill, which includes factoring multiple terms, is often required when simplifying complex expressions involving the power of a quotient rule.

By mastering these prerequisite topics, you'll build a strong foundation for understanding and applying the power of a quotient rule. Each concept contributes to your overall comprehension, making it easier to grasp this more advanced topic. Remember, in mathematics, each new concept builds upon previous knowledge, so taking the time to solidify these prerequisites will pay dividends in your future mathematical endeavors.
