(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For what values does the limit exist?

[tex]Lim_{n\rightarrow}\infty[/tex]([tex]\frac{z}{z conjugate}[/tex])^n

2. Relevant equations

3. The attempt at a solution

[(x+iy)/(x-iy)]^n

I just don't know how to tell when it exists. For even values of n because then there would be no sign changes?
