x=2

Explanation:

Even if there's nothing to "solve", strictly speaking, I assume you simply want to simplify log_{12}(144), and it's very simple:

log_{a}(b)=x means that x is the exponent that you must give to a to obtain b. Namely: a^x=b.

This means that, in your case, log_{12}(144) is the exponent that you must give to 12 to obtain 144, and since 144=12^2, that exponent is 2. So,

x=log_{12}(144)=2
