ANSWER: Fermat's little theorem says x^p == x (mod p). Think of this as saying x^{p-1} == 1 OR x == 0 (mod p). NowThis implies that x^{5K(p-1)+1} == x^{3-1}^ (mod p) for any K. So we combine p=2, soK=4 it(trivial); isp=5, K=1 mod(direct application of FlT; and p=3, K=2 (the case you are looking at). In every case we show x^5 == x. --[[User:TomHyer|Tom Hyer]]
