## Homework Statement

I have some trouble understanding some of my math homework maybe somebody can help me out?

1) find all the values of

ln(e)

(-1)^i

I know that i am going to have to use eulers formula in some way i believe but im not really sure what the question is asking, what does it mean all the values?

2)let z= x+iy, where both x and y are real. find the real and imaginary parts for e^(1/z).

i figure i would have e^(1/x+iy) but where do i go from there?

3) rewrite in the polar form

(√(z))^(1/n), now this i dont really understand. I can really easily change something like 4 +6i to polar form but this i dont get.
