The Attempt at a Solution



Don't really know were to begin. If anyone could tell me which method to use that would be great. I can't think of any way to solve this.

That equation is NOT linear. I don't know if it will work but my first thought is to change coordinates to get rid of that "xy" term.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
