Let $R $ be a commutative ring with 1 and $s $ a nonnilpotent element of $R $ such that for each idempotent $e $ of $R $ there exists a natural number $n_e $ such that either $s^{n_e}e=0$ or $s^{n_e}(1-e)=0$. Can we deduceddeduce that for each idempotent $e $$e$ of $R $$R$ either $s^me=0$ or $s^m(1-e)=0$ for a fix natUralnatural number $m $?
