True and false propositions with quantifiers. Answer the following questions in the space provided below. For each proposition below, first determine its truth value, then negate the proposition and simplify (using DeMorgan's laws) to eliminate all symbols. All variables are from the domain of integers. Consider the predicates defined below. Take the domain to be the positive integers. P(x): x is a perfect square Q(x): x is prime Invent an example of a true proposition using quantifiers (V and 3); at least one of the logical operations from the predicates P(x) and Q(x). Invent an example of a false proposition using quantifiers (V and 3); at least one of the logical operations from the predicates P(x) and Q(x). Don't just write followed by your response to.
