4log(3/8)
or log(81/4096) . . . because 4log(3/8) = log((3/8)^4)

We can do some good old fashioned factoring to turn the expression into:
4 ( log3 - log8 )
Then there is a rule that logA - logB = log(A/B), so
4 ( log(3/8) )
Also, we have the rule that P * logC = log(C^P), so
log( (3/8)^4 )
which is log( 81/4096 )
