need help please!!!!!

(fraction)

_____1____

9x^-2 y^-1

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

or

y^(-4) = 1/y^(-4)

the nine will stay where it is.
