need help please!!!!!
I'm not exactly sure what you want to do but i'm assuming you want your exponents positive? just put the varibles with the negative exponents in the numerator. whenever you have a negative exponent that you want to make positive, just change it to the other side of the fraction it was orginally on. example:
1/x^(-2) = x^2
y^(-4) = 1/y^(-4)
the nine will stay where it is.
