# Math Help - Easy Log Problem. Help

1. ## Easy Log Problem. Help

The problem asks you to evaluate:
Log(base 3)72 WITHOUT A CALCULATOR.

You are given the value of Log(base 3)6 and of Log(base 3)4

How do I solve!!!

Since $\log (xy) = \log (x) + \log (y)$ in any base, find $\log_{3} (3 \times 4 \times 6)$. You should know that $\log_{3} (3) = 1$, so add 1 to the other two logs you were already given.
