Question 3: Without using a truth table, apply the laws of standard logic equivalence to verify ~(p v ~q) V (~p ^ ~q) = ~p State the law whenever it is applied. Question 4: Without using a truth table, apply the laws of standard logic equivalence to verify ~((~p ^ q) v (~p ^ ~q)) ≡ (p ^ (~ (~p v q))) v (p ^ q) State the law whenever it is applied. Question 5: Recalling the operator 'exclusive-or' ⊕: p ⊕ q ≡ (p v q) ∧ ~(p ^ q) a. Simplify p ⊕ p b. Simplify (p ⊕ p) ⊕ p c. Show that (p ⊕ q) ⊕ r ≡ p ⊕ (q ⊕ r) d. Show that (p ⊕ q) ∧ r ≡ (p ∧ r) ⊕ (q ∧ r)

Use a truth table, similar to those in Examples 1–4, to prove each rule of logic. The rules in Exercises 25–27 are known as simplification, amplification, and conjunction, respectively $$\frac{p \wedge q}{p}$$
