Question

By the series of logical equivalences show that ~( ↔ ) ≡ ↔ ~ are logically

equivalent.​

Answer 1

Step-by-step explanation:

A compound proposition that is always True is called a tautology. Two propositions p and q are logically equivalent if their truth tables are the same. Namely, p and q are logically equivalent if p ↔ q is a tautology. If p and q are logically equivalent, we write p ≡ q.
