The powerful properties of normal subgroups with 3 generating elements and factor groups G/Z(G)in finite p-group G was studied.The necessary conditions of powerful property about normal subgroups with 3 generating elements in finite powerfulp-groups(p≥5)are given by using minimal counter example order method
the powerful embedded property and the commutator formula of metabelian group. Moreover
by discussing the conditions which the derived group G′of finitep-group G met
the sufficient condition and the necessary condition of powerful property about factor group G/Z(G) of Gare given.
