1. Given that p and q are True and r and s are False, find the truth value of the statement. (~r) = (pA(r → (~qV~s))) 2. (а) Rewrite the statements in the form of " i. x, No irrational numbers are integers. The number -4 is not equal to the square of any real number. ii. (b) Rewrite the statements in the form of "3 i. ii. x, Some exercises have answers. Some real numbers are rational. (c) Determine the truth value of the statements where D = E = {-9, –3,0,3,9}. Hence, write the negation of the statements. i. i. x in D, 3y in E such that x +y = 0. 3x in D such that Vy in E, x + y = y. 3.
