(d) Define the semidirect product Z/5Z × (Z/5Z)* to have Z/5Z × (Z/5Z)* as its underlying set, but with binary operation (a, b) · (c,d) = (a + bc, bd). . Show that Z/5Z × (Z/5Z)* is a group with this operation and that it is nonabelian. (e) Show that o: G(K/Q) → Z/5Z × (Z/5Z)* is a group isomorphism.
