When there are parentheses with an exponent after them, sometimes we can apply the exponent to everything in the parentheses, and sometimes we can not. What we need to look at is what operation is happening inside the parentheses: if there is a sum or difference, we can not apply the exponent to the terms inside the parentheses BUT, if there is a product or quotient, then each term inside the parentheses will get that exponent.
