## Homework Statement

((1-i)/(sqrt2))^42

express in x+iy form

## Homework Equations

z1/z1=(r1/r2)e^(i(theta1-theta2))

## The Attempt at a Solution

Ive found that (1-i) has r=sqrt2 so since r is sqrt2 and x=1 y=-1 so the angle is 7pi/4

so then I have (sqrt2e^(-i7pi/4)/sqrt2)^42

now from here is where I dont understand where to go to obtain x+iy form since it is raised to the 42 power and I dont have a e on the bottom
