Math Tips
The “Euler’s conjecture” is proposed by Leonhard Euler in 1769, and is related to “Fermat’s last theorem”. It states that for every integer n greater than 2, the sum of n –1 n^{th} powers of positive integers cannot itself be an n^{th} power. The conjecture was disproved by L. J. Lander and T. R. Parkin in 1966, when they found the following counterexample for n = 5: 27^{5} + 84^{5} + 110^{5} + 133^{5} = 144^{5}.
