Question

What is the value of y in the product of powers below?

Answer 1

You're trying to find the value of y that would result in 8^-2. When you multiply terms with the same base, you can add the exponents. 3+-5=-2 and -2-(-2) equals 0, so therefore y is equal to 0.

Answer 2

when multiplying you add the powers

3 +-5 = -2 so the power for y = 0
