Evaluate (5×6)^9: Solving a Multiple-Step Exponent Problem

To solve the expression $\left(5\times6\right)^9$, we apply the rule for the power of a product. This rule states that when you raise a product to a power, it is equivalent to raising each factor in the product to the same power. Mathematically, this is expressed as:

• $(a \times b)^n = a^n \times b^n$

In this specific problem, the factors are $5$ and $6$ and the exponent is $9$. Applying the power of a product rule, we get:

• $\left(5\times6\right)^9 = 5^9 \times 6^9$

Therefore, the correct expression that corresponds to $\left(5\times6\right)^9$ is $5^9\times6^9$.
