WebProblem 7.6. Prove that Qpos is not isomorphic to Z. Proof. Suppose for contradiction that Qpos is isomorphic to Z where Qpos is a group under multiplication and Z is a group under addition. That means there exists an isomorphism f : Qpos → Z. Since f is an isomorphism, f is onto. That means for every y ∈ Z there is an x ∈ Qpos s.t. f(x) = y.
