Prove that a disjoint union of any finite set and any countably infinite set is countably infinite. Proof: Suppose A is any finite set, B is any countably infinite set, and A and B are disjoint. By definition of disjoint, A ∩ B = ∅ Then h is one-to-one because f and g are one-to one and A ∩ B = 0. Further, h is onto because f and g are onto and given any element x in A ∪...

15. Theorem 14.5 implies that Nx N is countably infinite. Construct an alternate proof of this fact by showing that the function ф : N x N 2n-1(2m-1) is bijective. N defined as ф(m,n) It is also true that the Cartesian product of two countably infinite sets is itself countably infinite, as our next theorem states. Theorem 14.5 If A and B are both countably infinite, then so is A x B. Proof....
