new problem now..

question:

z=((4+4jsqrt3)/(-6+6j))^2

so this time i was thinking to multiply by the conjugate and then i can use modulus= sort a^2 +b^2 and arctan(b/a)=argument... then use de moivres theorem to deal with the square... im just reading the text book and trying to get what I can as I started the course late

thanks for any help
