Build a truth table; assuming p and r are false, and that q and s are true, find he truth value of each proposition:
p (q r)

For each pair of propositions P and Q , state whether or not P = Q
P= (pq)r , Q= p(qr)

T₂(x, y) is the propositional function \"x is taller than or the same height as y.\" Write the following proposition in words:
xy T₂(x, y)

Assume xy P(x, y) is false and that the domain of discourse is nonempty. Prove if the following is false:
xy¬P(x, y)
