log4 4^2+log2 4)^2 - log12 12-2

Let's break down the problem step by step:

log4 4^2 = 2
log2 4 = 2
(log2 4)^2 = 4

So, we can rewrite the expression as:

2 + 4 - log12 12-2

Now, let's simplify the last term:

log12 12-2 = log12 (1/144) = -2

Substituting this value, we get:

2 + 4 - (-2) = 8

Therefore, the final answer is 8.
