Prove or disprove (without using a truth table): (p^q) rightarrow (q rightarrow p) is a tautology....
Prove the following is a tautology (without using a truth table) [(p →q) (q + r)] → (p → r)
prove the equivalence without using truth tables P → (Q → S) ≡ (P ∧ Q) → S.
Please generate a truth table and answer "Is the compound statement a tautology?" (p ↔ q) ↔ [ (q → p) ∨ (p → ~ q) ]
Prove or disprove the following expression. (Prove: using Boolean algebra. Disprove: using truth table.) (NOT is presented by -.) 1. a + b (c^- + d)^- = a^-b^- + a^-cd^- 2. ab^- + bc^- + ac^- = (a + b + c) (a^- + b^-+ c^-) 3. a^- + bd^-^- (c + d) + ab^-d = ac^-d + ab^-cd + abd
Prove that (¬q ∨ (¬p → q)) →p is a tautology using propositional equivalence and the laws of logic. Step Number Formula Reason
