A powerful resemblance. (Posted on 2015-07-12) Difficulty: 3 of 5

1. Let a and b be consecutive non-zero whole numbers. Let C be the square of their sum, less their product, i.e. C = (a+b)^2-ab. Let n be a whole number.

Claim 1: C^n = (A+B)^2-AB, for some whole numbers A,B.

Prove it, or find a counter-example.

2. Let a and b be ANY relatively prime whole numbers, and perform the same operation.

Claim 2: C^n = (A+B)^2-AB, for some whole numbers A,B.

Any exceptions?
