Hi,

I'm not too confident about some mod simplification.

I am wondering if anyone can help me simplify this:

2^(28) (mod 37)

Basically, I don't know how to get it to become a 2^x = 1 or -1 (mod 37)

Here's my attempt

1) (2^2) (3^2) = -1 (mod 37)

Therefore...

Well, let's face it, I have no idea where to go from there.

Thanks for any help

P.S.: Please forgive me, I'm having some trouble with LaTex right now :(
