I know I should know this because I've done it all already, but logs were never my strong point. But I think I can vaguely remember a log rule that states that ln(x)^y = yln(x). I'm pretty sure you could use that here. You're also gonna need to clean things up a bit. I'm positive there's some sort of factoring or grouping you could do somewhere, but am way to tired to do it. Besides, I have my own homework to do. >=]
