Answer to Question #284548 in Discrete Mathematics for Shin

Question

(p^q)v(P ^ Q ^ R)

Answer 1

$(p\land q)\lor(p \land q \land r)=(p\lor (p \land q \land r))\land(q\lor (p \land q \land r))$

$p\lor (p \land q \land r)=p\lor (q\land r)=(p\lor q)\land (p\lor r)$

$q\lor (p \land q \land r)=q\lor (p\land r)=(p\lor q)\land (q\lor r)$

$(p\lor q)\land (p\lor r)\land (p\lor q)\land (q\lor r)= (p\lor r)\land (p\lor q)\land (q\lor r)$

$(p\land q)\lor(p \land q \land r)= (p\lor r)\land (p\lor q)\land (q\lor r)$
