Barrett · Answer 1

8^-2=1/8^2 so just use 8^-2

8^3*8^-5*8^y=8^-2

8^ (3-5+y) = 8^-2

3-5+y=-2

y=0

Mistress · Answer 2

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.
