This paper proves that any positive integer solution to the equation
,where x,y, and z are all greater than 2, must satisfy that A,B, and C have a common prime factor. We use the method of a special case of the modularity theorem for elliptic curves, originating from Andrew Wiles. We proceed in two stages. We first state and prove a main lemma that reduces our problem to showing that a certain elliptic curve has no rational points. The lemma shows that if A,B and C are pairwise coprime, then there exists an elliptic curve E that is modular and has rank at least 1, and we then show that this elliptic curve is modular and use this fact to derive a contradiction. The additional result shows that E has no rational points of infinite order, except for the trivial ones. This contradicts the fact that E has rank at least 1, and hence implies that A,B, and C cannot be pairwise coprime.
