Video Solution

Solution Steps

00:00 Simplify the following problem
00:04 According to the laws of exponents, the multiplication of exponents with an equal base (A)
00:07 is equal to the same base raised to the sum of the exponents (N+M)
00:11 We will apply this formula to our exercise
00:16 We'll maintain the base and add together the exponents
00:23 This is the solution

Step-by-Step Solution

To simplify the expression 97×93×95 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+57 + 3 + 5.
  • Step 3: Perform the addition: 7+3+5=157 + 3 + 5 = 15.

This results in the expression simplifying to 97+3+5=915 9^{7+3+5} = 9^{15} .

Therefore, the expression 97×93×95 9^7 \times 9^3 \times 9^5 simplifies to 915 9^{15} .

The correct answer is choice (1): 97+3+5 9^{7+3+5} .

Answer

97+3+5 9^{7+3+5}
