We have to solve the problems of discrete mathematics.

Use De Morgan's law for quantified statements and the laws of propositional logie to show the following equivalences: (a) -Vr (P(r)A-Q(z)) = 3r (-P(z) V Qtr) (b) -Vr (-P(r)-Q(u)) = 3r (-P(r) A-Q(r)) (e) -ar (-P(z) V (Q(r}A¬R(a))) = (P(x) A (-Q(z) V R(x)))

Use De Morgan's law for quantified statements and the laws of propositional logie to show the following equivalences: (a) -Vr (P(r)A-Q(z)) = 3r (-P(z) V Qtr) (b) -Vr (-P(r)-Q(u)) = 3r (-P(r) A-Q(r)) (e) -ar (-P(z) V (Q(r}A¬R(a))) = (P(x) A (-Q(z) V R(x)))
