Complete the Expression: Finding (y×a) Raised to the Power of 5

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Apply the appropriate formula
• Step 3: Perform the necessary calculations

Now, let's work through each step:
Step 1: The problem provides the expression $\left(y \times a\right)^5$ and asks us to write the corresponding expanded expression.
Step 2: We'll use the exponent rule for the power of a product, which states that $(xy)^n = x^n \times y^n$.
Step 3: Applying this rule, we raise each factor inside the parentheses to the fifth power: $y^5 \times a^5$.

Therefore, the solution to the problem is $y^5 \times a^5$.

Among the given choices, Choice 1: $y^5 \times a^5$ is the correct expression.
