Question 3 (Block I Unit 2) – 20 marksYou should be able to answer this question after you have studied Block I Unit 2.(1) By constructing 0-1 value-tables for the following two expressions, determine whether ornot they are equivalent:(a) (p ^ q) _ (r ^ p): [5](b) p ! (q ! r): [5](2) Without the use of 0-1 value-tables Önd the simplest forms for each of the followingexpressions. The Önal expression must only use the operations: negation, conjunction anddisjunction.(a) (p ! q) _ p: [2](b) p $ (p ! q): [3](3) Draw the combinatorial circuit that represents the Boolean expression(x1 ^ x2) _ (x1 ^ x3)^ x3:
