Understanding the Problem

When dealing with algebraic expressions, it's essential to understand the rules of operations to simplify and solve equations. In this article, we'll focus on performing indicated operations, specifically exponentiation, on algebraic expressions. We'll use the given problem, $\left(x^3 y^5\right)^3$ , as a case study to demonstrate the steps involved.

The Power of Exponentiation

Exponentiation is a fundamental operation in algebra that involves raising a number or expression to a power. In the given problem, we're asked to raise the expression $x^3 y^5$ to the power of 3. To solve this, we'll apply the rule of exponentiation, which states that when a power is raised to another power, we multiply the exponents.

Applying the Rule of Exponentiation

To apply the rule of exponentiation, we'll follow these steps:

Identify the base and exponent: In the given expression, $x^3 y^5$ is the base, and 3 is the exponent.
Multiply the exponents: We'll multiply the exponents of the base, which are 3 and 5, to get the new exponent.
Apply the exponent to the base: We'll raise the base, $x^3 y^5$ , to the power of the new exponent.

Simplifying the Expression

Now that we've applied the rule of exponentiation, we can simplify the expression. We'll multiply the exponents of the base, which are 3 and 5, to get the new exponent.

\left(x^3 y^5\right)^3 = x^{3 \cdot 3} y^{5 \cdot 3} = x^9 y^{15}

Interpreting the Result

The final expression, $x^9 y^{15}$ , represents the result of raising the original expression, $x^3 y^5$ , to the power of 3. This means that the exponent of $x$ is 9, and the exponent of $y$ is 15.

Conclusion

Performing indicated operations in algebra requires a clear understanding of the rules of operations, specifically exponentiation. By applying the rule of exponentiation, we can simplify complex expressions and solve equations. In this article, we've demonstrated the steps involved in performing indicated operations, using the given problem, $\left(x^3 y^5\right)^3$ , as a case study.
