A negative exponent changes where a value is in a fraction: a negative exponent in the top of a fraction moves the term to the bottom and the exponent becomes positive, and a negative exponent in the bottom of a fraction moves the term to the top and the exponent becomes positive. Here, we do examples where we get rid of the negative exponents first, and then simplify the rational products from there. Remember that you can cancel entire factors that are the same in top and bottom.
