7. Compute the truth values of the following symbolic statements, supposing that
the truth value of A, B, C is T, and the truth value of X, Y, Z is F.
a) [(A^ X) V (¬A^ ¬X)] → [(A → X) ^ (X → A)]
b) [(A^X) Y] → [(A → X) ^ (A → Y)]
c) [A→ (X^Y)] → [(A → X) v (A → Y)]
8. Construct a truth table to determine which of the five semantic properties the
wff has. Write your determination under your table.
(a) {¬A v ¬B, ¬A→B, ¬А ^B}
(b) {¬Av ¬B, ¬A→B, A→B}
