You can put this solution on YOUR website!
There's nothing to solve, it's not an equation.
Maybe you want to simplify it ?

%28%28x-y%29%2F%28x%5E3y-2x%5E2y%5E2%2Bx%2Ay%5E3%29%29%5E%281%2F2%29
= %28%28x-y%29%2F%28xy%2A%28x%5E2-2xy%2By%5E2%29%29%29%5E%281%2F2%29
= %28%28x-y%29%2F%28xy%2A%28x+-+y%29%5E2%29%29%5E%281%2F2%29
= %281%2F%28xy%2A%28x+-+y%29%29%29%5E%281%2F2%29
= sqrt%28xy%2A%28x-y%29%29%2F%28xy%2A%28x-y%29%29
