Solve: 4^a × 8^a × 2^a - Multiplying Powers with Same Exponent

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

• Step 1: Identify the common exponent in all terms.

• Step 2: Apply the power of a product rule to combine the terms.

Now, let's work through each step:
Step 1: We have the expression $4^a \times 8^a \times 2^a$, where each base is raised to the same power, $a$.
Step 2: Using the power of a product rule, we can combine the terms into a single expression: $(4 \times 8 \times 2)^a$.
Therefore, in terms of the choice list, the corresponding expression is $\left(4\times8\times2\right)^a$, which is choice 2.
