Expert Answer:

Its entirely upto you if you want to solve the question using log tables or not, they merely help in simplifying mathematics. they dont change the physics.
Eq to find x = 3^23
take log of both sides
thus log x = 23 log 3  (using properties of log i.e. log a^b = b log a)
find log 3
then take antilog on both sides to find the value of x
