Complex numbers problem need help

I hope you don't get mad but this is another long problem i have.

I really want to know how to do this i know what you mean but i don't how to start.

**Given the Complex numbers** Z1= -3+sqr.root of 3i and Z2= -1-i

**respond to the following:**

sketch a reasonable graph of Z2 (in the complex plane)

write Z2 in polar form

find the modulus of Z1

find (Z1) (Z2). Leave your answer in polar form

find (Z2)^7 (Hint: Try Big D's Theorem)

Z1 and Z2 i couldn't type it well but it suppose to be the 1 and 2 a little bit below the Z.
