Abstract:
It is conjectured that Euler possessed an elementary proof of Fermat's theorem for $n=3$. In this note, we show that this opinion is rather credible, because Euler's results can justify an elementary proof of the nonexistence theorem for nontrivial integer solutions of the equation $x^3+y^3=z^3$.
