Solve (1-i)^n = -512 - 512i

    Solve [tex](1-i)^n = -512 - 512i[/tex] for n.
    :wink:

    as in you need help with it? Or a problem for us to do?

    Anyhow...it looks relatively simple.

    I'm thinking n = 19

    Even I can do that one.

    The fact that [itex](\sqrt{2})^10= 512[/itex] makes that pretty trivial.

    mathwizarddud, many of us seem to be slightly irritated you constantly post these problems here in the *Homework Help* section. You may think these problems are interesting, and I'm sure they interest some other people as well, but please, post these in the general math section, all under a single thread, named something obvious like "Simple Math Problems" or alike.

    Gib Z, whether or not the question is a real homework question is irrelevant. If it's a standard textbook question, it belongs in the HW forums, and the OP is required to show original effort. Otherwise the Math forums just become a backdoor to avoiding our Guidelines for homework.
