Prove the following using the method suggested: (a) Prove the following either by direct proof or by contraposition: Let a ∈ Z, if a ≡ 3 (mod 5) and b ≡ 2 (mod 5), then ab ≡ 1 (mod 5). (b) Prove the following by contradiction: Suppose a, b ∈ Z. If a² + b² is odd, then (2|a) ⊕ (2|b), where ⊕ is the exclusive disjuntion, i.e. p ⊕ q = (p ∨ q) ∧ ¬(p ∧ q). (d)...
