While they are dead no. While they were alive—yes, they could. (This is interesting in that, properly performed, (a specified) computation gets the same result, whatever the circumstances. More generally, Fermat argued that: for integers a, b, c, and n, where n>2, a^n+b^n=c^N:
had no solutions
was provable
He might have been wrong about the difficulty of proving it, but he was right about the above. If perhaps for the wrong reasons. (Can we prove Fermat didn’t have a proof?))
