In problems 3-8 determine whether the statement is true or false. Justify your answers. 3.) Ifo: R → R' is a ring homomorphism then 0: (R, +) → (R', +') a is a group homomorphism.

C. If ©: (R,+) → (R', +') is a group homomorphism, where Rand R' , are rings then 0: R = R' is a ring homomorphism. 5. If O: R R' is a ring homomorphism and ker(0) = {0} then o is not one-to-one. 6. Z is an ideal in Q. 7.) If R' is a subring of R then R' is an ideal of R. 8 The rings Z/8Z and Zg are isomorphic rings.
