I'm not sure if 'a' is the base of the log or one of the factors...
IF 'a' IS PART OF THE PRODUCT:
First rule:
log a*b = log(a) + log(b)
log (a * 3 * x^3 * y)
log (a) + log(3) + log(x^3) + log(y)
Next rule:
log (a^n) = n log(a)
log (a) + log(3) + 3 log(x) + log(y)
HOWEVER, IF 'a' IS THE BASE OF THE LOGARITHM:
log[a](3 * x^3 * y)
log[a](3) + log[a](x^3) + log[a](y)
log[a](3) + 3 log[a](x) + log[a](y)

enough now! i understand that sometimes when you do your homework, there's a question that you just don't get, or you keep getting the same wrong answer. while we're all willing to help in that situation, no one is here to pass your course for you, and it's not going to help in the exam anyway. there is no yahoo answers workstation handed out with your paper, so suck it up, go to class, and study!

You are never going to learn if you just post all of your homework questions here.
