I am guessing all of your minus signs are negative exponents. So you have (x^(-1) + y^(-1))/x^(-2)y^(-2). The first thing I would do is separate this into two separate fractions, x^(-1)/x^(-2)y^(-2) + y^(-1))/x^(-2)y^(-2). Now, this is the same as x^2*y^2/x + x^2*y^2/y. So x*y^2 + x^2*y. This is the simplified form.
