        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.
