Rewrite each statement so all negation symbols immediately precede predicates. use math symbol at http://math.typeit.org/ (a) \( \neg \exists x \exists y(\neg P(x) \wedge \forall x \forall y(\neg Q(x, y) \vee R(z))) \) (b) \( \neg(\forall y \exists z \neg P(x) \vee \exists x \exists y Q(x, y) \wedge \neg \forall x \forall y R(y, x)) \)
