Question

Please help prove these and state equivlance/inference laws used

a. ¬(p O q) = (p → q)
b. (р^ -9) — (p Өr) + -руqvar
(p → q) v (p → r) → p → (q v r)
C.

Expert Solution

Step 1

To prove the following using equivalence law:

$(a) . \neg (p \oplus q) \Leftrightarrow (p \leftrightarrow q)$

$(b) . (p \land \neg q) \to (p \oplus q) \Leftrightarrow \neg p \lor q \lor \neg r$

$(c) . (p \to q) \lor (p \to r) \Leftrightarrow p \to (q \lor r)$

Step by step
