What is Fermat's last theorem?
and How is that related to primes numbers of form 3x+1 and 3x+2

 FLT states: If n is an integer greater than 2, then there are no non-trivial integer solutions to the equation $$x^n+y^n=z^n$$. One reduction for the proof is that it would be enough to prove the case when $$n$$ is prime (or 4). The case $$n=4$$ is classical. It turns out that argument for primes of the form $$3k+1$$ is different than for primes of the form $$3k+2$$. *warning, Latex seems out of whack today*
