    Square routing a log

    How would I solve...
    9 = log2x2


    Surely that means 2^9=x^2=512
    So x=+-(sqrt)512??

    But that's not the answer in the book, it gets x=+-3??

    Sorry for not using Latex, I'm not too familiar with it but these are simple equations so I hope it doesn't pose too much of an issue.
