Can there be a homomorphism from Z8 ⊕Z2 onto Z4⊕Z4 ? Give reasons for your
answer.
Let us prove that there is no homomorphism from onto using method of contradiction. Assume that is a surjective homomorphism. Since we conclude that the surjection is a bijection, and hence is an isomomorhism. Taking into account that isomorphisms preserve orders of elements and contains the element of order 8, but all elements of have order less or equal to 4, we conclude that our assumption is not true. Consequently, there is no homomorphism from onto
