abstract = {This article shows using the Fermat-Wiles theorem that the equation $x^{-n}+y^{-n}=z^{-n}$ has solution in integer numbers only the case $n = 1$ and $n = 2$ (same as the Fermat theorem). The method of the proof is elementary except of a reference to Fermat-Wiles theorem. It can be handled by talented pupils in secondary schools as well.},
