Question

Use De Morgan's law for quantified statements and the laws of propositional logic to show the following equivalences:

**Transcription for Educational Website:** **Logical Equivalence in Predicate Logic** In the study of logic, particularly predicate logic, we often deal with statements involving quantifiers and logical connectives. Below is an expression demonstrating logical equivalence: (b) \( \neg \forall x (\neg P(x) \rightarrow Q(x)) \equiv \exists x (\neg P(x) \land \neg Q(x)) \) **Explanation:** This expression is a logical equivalence that shows the transformation between two statements: - The left side, \( \neg \forall x (\neg P(x) \rightarrow Q(x)) \), represents the negation of a universal quantification. It reads as "It is not true that for all \( x \), if \( P(x) \) is false, then \( Q(x) \) is true." - The right side, \( \exists x (\neg P(x) \land \neg Q(x)) \), represents an existential quantification. It reads as "There exists an \( x \) such that \( P(x) \) is false and \( Q(x) \) is false." The equivalence illustrates how negating a universal statement can be converted into an existential statement with different conditions. This concept is fundamental in simplifying and transforming logical expressions within proofs and logical reasoning.
