The original LHS can actually be simplified to r in about 3 steps as Mark was hinting at earlier The first part of your statement, "~p" says that p is false That means that "p^r" is false so that statement reduces to " (~q^r)v (q^r)" If q is false, "q^r" is false so we must have "~q^r" and so rTitle Author suzyroman Created Date 9/3/21 543 PMU T S V W P Q R Hence immidiate neighbour of w are V and P Therefore Option 3 is the right answer Download Solution PDF Share on Whatsapp India's #1 Learning Platform Start Complete Exam Preparation Daily Live MasterClasses Practice Question Bank Mock Tests & Quizzes
P v (q r) º (p v q) ( p v r) Notice that the main connective always changes between an and an v The other connective, then, is the one you put with the other componentsThe systematic way to show this is to bring it to conjunctive normal form (this can be more easily done with carnaugh tables, but that would probably count as a truth table) We start with the statement ( ( p ∨ q) → r) ↔ ( ( p → q) ∨ ( p → r)) My strategy here is to rewrite the equivalence as a conjunctive form with factors in txt hdrsgml accession number conformed submission type 8k public document count 24 conformed period of report item information regulation fd disclosure item information financial statements and exhibits filed as of date
