The correct Answer is:
To solve the expression `~(~P ∧ Q) ∧ (P ∨ Q)`, we will follow a step-by-step approach using logical equivalences. ### Step 1: Rewrite the Expression We start with the expression: \[ ~(~P \land Q) \land (P \lor Q) \] ### Step 2: Apply Double Negation Using the double negation law, we can simplify `~(~P)` to `P`. Thus, we have: \[ (P \lor Q) \land (P \lor Q) \] ### Step 3: Apply De Morgan's Law Now, we can apply De Morgan's Law to the negation of the conjunction: \[ ~(~P \land Q) = P \lor ~Q \] So, we rewrite our expression as: \[ (P \lor ~Q) \land (P \lor Q) \] ### Step 4: Distribute the Terms Now, we can distribute the terms: \[ (P \lor ~Q) \land (P \lor Q) = P \lor (Q \land ~Q) \] ### Step 5: Simplify Using the Law of Non-Contradiction Since \( Q \land ~Q \) is always false (denoted as \( \emptyset \)), we simplify this to: \[ P \lor \emptyset = P \] ### Final Result Thus, the original expression `~(~P ∧ Q) ∧ (P ∨ Q)` is logically equivalent to: \[ P \]

To solve the expression `~(~P ∧ Q) ∧ (P ∨ Q)`, we will follow a step-by-step approach using logical equivalences. ### Step 1: Rewrite the Expression We start with the expression: \[ ~(~P \land Q) \land (P \lor Q) \] ...
