Admirable Quote by Pierre de Fermat

“To divide a cube into two other cubes, a fourth power, or in general any power whatever into two powers of the same denomination above the second is impossible, and I have assuredly found an admirable proof of this, but the margin is too narrow to contain it.” quote by Pierre de Fermat

About This Quote

Source Letter: Correspondence with a friend, 1654

Fermat claims a proof that a power higher than the second cannot be expressed as sum of two like powers, noting his proof is too long for the margin.

In simple terms: Higher powers cannot be split into two equal lower powers.
