Question IF ( G, * ) is an abelian group then discuss correctness of each of the options ... a) a = a-1 for all a $\epsilon$ G b) a2 = a for all a $\epsilon$ G c) (a*b)2 = a2 * b2 for all a,b $\epsilon$ G d) G is finite order My ... b*a = a*b // cancelling a using left cancellation law and b using right cancellation law Therefore G is abelian group Given statement is correct D) PLEASE HELP ME ..
