Here is the 2nd one which asks to simplify the whole thing as a logarithm. Again, not sure how to take the integers at the end and convert them into log form. (Headbang) Thanks.

Thank you, but im a bit confused how to go about changing the base, or if i even have to to log base 4.

ps., the correct answer is log base 4 (xy^2 over 64) - October 6th 2009, 11:44 AMe^(i*pi)
We know that

Note that because

As (see the rule above)

So overall we can rewrite it as

You can then combine the logs to give:
