http://www.wolframalpha.com/ just paste it there and modify it till it looks like what you have I will copy this (x^2y^-2/x^-3y^4)^-2(x^-2y^3/x^3y^-1)^2 http://www.wolframalpha.com/input/?i=%28x%5E2y%5E-2%2Fx%5E-3y%5E4%29%5E-2%28x%5E-2y%5E3%2Fx%5E3y%5E-1%29%5E2 is this what it looks like in your book or whatever?
