**Amy**, Sunday, November 14, 2010 at 2:36pmI just solved it and i know how to get 1 / b^(3y+6) as the answer

but, if for the exponent -4y+7 if it isn't -(4y+7) I wouldn't move it to the bottom of a fraction?

a^{3}= 1/a^{-3}

sometimes teachers have beginning students move them around just for practice.
