remember the general theme here: always try to get a COMMON BASE whenever you're dealing with exponentials on both sides.
if you're having difficulty discerning what that common base should be, then it's always a good idea to use primes (as is done in this problem: note that the first step is to break 4 down into 2^2 and to break 10 down into 5*2).
