## Homework Statement

Prove that (z̄ )^k =(z̄ ^k) for every integer k (provided z≠0 when k is negative)

## Homework Equations

## The Attempt at a Solution

I let z=a+bi so, z̄ =a-bi

Then I plugged that into one side of the equation to get

(a-bi)^k

I was going to try to manipulate this to get [(a-bi)^k]

But I don't know where to go from here, or even what to do...

Please HELP!
