In problems 3-8 determine whether the statement is true or false. Justify your answers. 3.) If O: R = R' is a ring homomorphism then 0:(R, +) → (R', +') is a group homomorphism.
4. If 0:(R, +) → (R', +') is a group homomorphism, where R and R' are rings then o: R = R' is a ring homomorphism. 5 If O: R R' is a ring homomorphism and ker(0) = {0} then o is a not one-to-one. 6.) Z is an ideal in Q. If R' is a subring of R then R' is an ideal of R. 8.) The rings Z/8Z and Zg are isomorphic rings.
