Complex Numbers - Help please.

Hello there,

I'm really struggling with the following problem and would be VERY grateful if somebody could help me out, i've done some work but i want to check if i'm on the right track.

Consider the following Complex variables

(i) 2 + j5

(ii) - 4 + j10

(iii) - 6 - j3

Questions:

1) Multiply (i) and (ii) above by first converting to Polar form and express the result in Polar form.

2) Divide (ii) by (iii) above by first converting to Polar form and express the result in Polar form.
