a) in every group G, for all a,b members of G, and for all n member of Z(integers): (a^-1 * b * a)^n= a^-1 * b^n * a

(Do you have to use induction for this, because i think you do, but i am unsure?)

b) Every group table for a finite group is a Latian square, that is, each element of the group appears exactly once in each row and each column.
