Hey

It's been a while since I posted here, but here goes:

I have to (in basic terms) work out what:

$\displaystyle 72^{5712} mod 101$ is,

I've started by applying Euler's theorem and moved it down to:

$\displaystyle 72^{100x57 +12}$

but I'm stuck, as I'm not sure how this is going to give me a final result.
