Let P(x) and Q(x) be predicates and suppose D is the domain of x. In 55-58, for the statement forms in each pair, determine whether (a) they have the same truth value for every choice of P(x), Q(x), and D, or (b) there is a choice of P(x), and D for which they have opposite truth values. ∃ x ∈ D , ( P ( x ) ^ Q ( x ) ) , and ( ∃ x ∈ D , P ( x ) ) ^ ( ∃ x ∈ D , Q ( x ) )

Solution Summary: The author analyzes whether given two statements have the same truth values for each choice of P(x),Q left (x) and D. Option (b) is true i.e.
