    Hey, so I'm here just going over some notes, I came across this:

    If z = 2 + 2(sq root)3j then find z^12.

    It wants the answer in both polar and rectangular form.

    So I think the answer in polar form is:

    3.997^12 < 719.64

    Now I want to convert it to rectangular form which I can do but when I do I get some big numbers which makes me thing I am completely wrong, some help please?

    Why not just use De Moivre's theorem?
