Answer 1

Answer:

First start by subtracting the exponents from top to bottom

let's start with a  so a^2 - a^-2     2 - (-2) = 4

Now B: b^-3 - b^2   so -3 - 2 = -5

This leaves you with a^4 b^-5

However you cannot have a negative exponent so B must cross over and move to the bottom to become positive

Don't forget about the squared outside the parentheses. Both exponents must be multiplied by two to get 8 and 10

Step-by-step explanation:

Answer 2

Answer is C. $\frac{a ^{8} }{b^{10} }$
