I got pi/3 for question b is that correct? And as for part c, I expanded and got 2 root 2 for the real number and negative 2 root 2 for the i number. What do I do next? Thank you.

Did you get

a 4

b** - **pi/3 ? 4 (cos(-pi/3)+ i sin (-pi/3))

|w| = 4 ?

To divide the complex numbers that are in 'polar form' divide the 'r' values and subtract the angles

I come up with

d. 1 (cos (pi/12) + i sin (pi/12) )
