This might seem like a very simple problem, because we could just say that the only possible solution is n = 1/2, which is not an integer. But I am curious as to how to prove that there is no solution, with no knowledge of rational numbers, just as we can prove that x^2 = 2 as no rational solutions without any knowledge of irrational numbers.(adsbygoogle = window.adsbygoogle || []).push({});
