What is the remainder when 132^75 is divided by 37?

I really am confused even though the problem gives a hint that I should use Fermat litle theorem

Do you know Fermat's little theorem?

$132^{75}=\left(132^{37}\right)^2\cdot 132$ , and now apply FlT .

Here is the theorem:

$a^{p-1}\equiv 1 \ \mbox{(mod p)}$

If $a\ne zp$.
