El último teorema de Fermat

De acuerdo con el último teorema de Fermat , no hay tres números enteros positivos a, b, c que satisfagan la ecuación,  a^n + b^n = c^n    para cualquier valor entero de n mayor que 2. Para n = 1 y n = 2, la ecuación tiene infinitas soluciones.
 

Some solutions for n = 1 are,
 2 + 3 = 5
 7 + 13 = 20
 5 + 6 = 11
 10 + 9 = 19

Some solutions for n = 2 are,
5^2 + 12^2 = 13^2     3^2 + 4^2 = 5^2    8^2 + 15^2 = 17^2    9^2 + 40^2 = 41^2
