Here are some log questions that I haven't been able to solve. The problem that I'm having is that the base is different in some of them which is throwing me off.

By the way, the first question has a little typo. The right side of the equation should say 2log9(x-3) instead of 2log5(x-3)

If you can't see that picture then here's a link:
