I 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?
by answer I meant b^-3y+6
You may put the exponents in the numerator or denominator.
a3= 1/a-3
sometimes teachers have beginning students move them around just for practice.
