2.1.3. Prove the following refinement of the uniqueness of the identity in a group: Let G be a group with identity element e, and let e', g E G. Suppose e' and g are elements of G. If e'g says that if a group element acts like the identity when multiplied by one element on one side, then it is the identity.) -g, then e, e. (This result
