Show that p → q and ¬q → ¬p are logically equivalent

The solution to this exercise is straightforward by constructing the truth table.

Truth table for the compound propositions p → q and ¬q → ¬p
Truth table for the compound propositions p → q and ¬q → ¬p

By looking at the truth table for the two compound propositions p → q and ¬q → ¬p, we can conclude that they are logically equivalent because they have the same truth values (check the columns corresponding to the two compound propositions)
