Hello everybody, I would like to have some help with these two questions: 1. Let be a finite nilpotent group and a minimal normal subgroup. Show that . 2. Let be a group and verifying nonabelian subnormal subgroups of . Prove that 1. I have already proved that must be abelian; , but I find no way of proving that using that the nilpotency of and each one of its characterizations. Any idea? Regards and thanks in advance. Sheila.
