1. Write 3 - sqrt(3i) in exponential form.

Choices:

A. 9e ^i 11pi/6
B. 9e ^i 5pi/3
C. 2 sqrt(3e) ^i 11pi/6
D. 2 sqrt(3e) ^i 5pi/3

2. Find the first rhree iterates of the function f(z) = z^2-c for c=1-2i, and z0= 1+i

Choices:

A. -1+4i, -15-8i, 219+194i
B. -1+4i, -16-6i, 220+192i
C. -1+4i, -16-6i, 221+194i
D. -1+4i, -16-6i, 219+194i

First person to answer (and explain) both answers correctly will receive best answer.

Thanks :)
