    You can apply a few properties of logarithms to solve this:

    1. If a = log b then 10^a = b. From this you can translate the '2' into a log term.
    2. Remember that A log B = log(B^A). Apply this to the '3 log4' term.
    3. Finally use the fact that logA - logB = log(A/B).

    Post back with what you get for a final answer.
