1. Use cardinality to show that between any two rational numbers there is an irrational number. Hint: Given rational numbers a < b, first show that [a,b] is uncountable. Now use a proof by contradiction. 2. Let X be any set. Show that X and P(X) do not have the same cardinality. Here P(X) denote the power set of X. Hint: Use a proof by contradiction. If a bijection:X→P(X)exists, use it to construct a set Y ∈P(X) for which Y...

using theorem 11.10 (First Isomorphism Theorem), Show that the set of positive real numbers with multiplication is isomorphic to the set of real numbers with addition. Theorem 11.10 First Isomorphism Theorem. If ψ : G → H is a group homomorphism with K = kerψ, then K is normal in G. Let ϕ : G → G/K be the canonical homomorphism. Then there exists a unique isomorphism η : G/K → ψ(G) such that ψ = ηϕ.
