A Proof of Beal's Conjecture

First, we classify mathematical expressions which consist of AX, BY and CZ according to the parity of A, B and C, so get rid of two combinations of AX, BY and CZ, for they have nothing to do with the conjecture. For the remaining two cases, we first prove the equation AX+BY=CZ by examples where A, B, and C have at least one common prime factor. Then prove each kind of AX+BY≠CZ by arithmetic fundamental theorem, the mathematical induction, the binomial theorem, the reduction to absurdity, and the interrelation between a sum of two odd numbers and an even number that served as the center of symmetry, where A, B, and C have not a common prime factor, and that each proof takes which it needs.
