Thanks, everyone.

1.Let G be an Abelian group with identity e and let n be some fixed integer. Prove that the set of all elements of G that satisfy the equation X^n = e is a subgroup of G. Give an example of a group G in which the set of all elements of G taht satisfy the equation X^2 = e does not form a subgroup of G.

2. Prove that an Abelian group with two elemtns of order 2 (dude, does that include the identity? I don't understand.) must have a subgroup of order 4.

3. U(14)="<5>"="<3>". (Now, I can demostrate that is true, but how to prove it, by claiming each group is a subgroup of the other? And why"<3>" ="<5>" with both order of 5?)

The toughest math problems aren't the ones that just sound advanced.
