Video Solution

Solution Steps

00:11 Let's simplify this problem.

00:15 Remember, when multiplying exponents with the same base, like A,

00:19 we keep the base and add the exponents together, N plus M.

00:24 Let's apply this to our example.

00:27 Keep the base the same and add up the exponents.

00:34 And there you have it, that's the solution!

Step-by-Step Solution

To simplify the expression $9^7 \times 9^3 \times 9^5$ , we will use the multiplication rule for exponents which applies to powers with the same base.

Step 1: Identify that all terms have the same base of 9.
Step 2: Add the exponents together since the bases are the same: $7 + 3 + 5$ .
Step 3: Perform the addition: $7 + 3 + 5 = 15$ .

This results in the expression simplifying to $9^{7+3+5} = 9^{15}$ .

Therefore, the expression $9^7 \times 9^3 \times 9^5$ simplifies to $9^{15}$ .

The correct answer is choice (1): $9^{7+3+5}$ .

Answer

$9^{7+3+5}$
