ab
Show that (Q*,*) is a group.
1.1
1.2
Let a, b be elements of a group G. Assume that a has order 5 and
a³b = ba³. Prove that ab = ba.
1.3 Let G be a group and Z(G) = {a € G:ax = xa for all x e G}. Show that Z(G)is
a normal subgroup of G.
Let G be a group and let p: G → G be the map p(x) = x-1.
(a) Prove that o is bijective.
(b) Prove that p is an automorphism if G is abelian.
Let a, ßE S, (Symmetric group), where a = (1,2)(4,5) and ß = (1,6,5,3,2).
