The correct Answer is:
To determine whether the statement `p ^^ (p implies q) = q` is under the law of detachment, we will analyze the components of the statement step by step. ### Step-by-Step Solution: 1. **Understanding the Law of Detachment**: - The law of detachment states that if we have two premises: 1. \( p \implies q \) (If p, then q) 2. \( p \) (p is true) - Then we can conclude \( q \) (q is true). 2. **Identifying the Components**: - The expression we need to analyze is \( p \land (p \implies q) \). - Here, \( p \land (p \implies q) \) means both \( p \) is true and \( p \implies q \) is true. 3. **Rewriting the Expression**: - We can rewrite the expression \( p \land (p \implies q) \) in a more logical format. - According to the law of detachment, if both \( p \) and \( p \implies q \) are true, then \( q \) must also be true. 4. **Evaluating the Expression**: - If we assume \( p \) is true, then \( p \implies q \) must also be true for the law of detachment to apply. - Therefore, if both \( p \) and \( p \implies q \) are true, we conclude that \( q \) is true. 5. **Final Conclusion**: - Thus, we can conclude that \( p \land (p \implies q) \) logically leads to \( q \). - Therefore, the statement \( p \land (p \implies q) = q \) holds true under the law of detachment. 6. **Truth Value**: - Since the statement is true, we write 'T' for True. ### Final Answer: The truth value of the statement `p ^^ (p implies q) = q` is **T** (True).
