Question regarding separable extension












0












$begingroup$


If $K$ is a field extension of $F$ and if $alpha$ $in$ K is not separable over F, show that $alpha^{p^{m}}$ is separable over F for some $mgeq 0$. Where $p=char(F)$.



I have been trying it for hours. Any help is appreciated. Thank you
