Math Problem Statement

Which of the following is equivalent to P ⇒ Q?

2 points ~ P ⇒ Q ((P ∧ Q) ∨ (¬P ∨ ¬Q)) P ⇒ (Q ∧ P) P ⇒ ~Q ∧ P

Solution

Let's break down the equivalence for P ⇒ Q.

  1. P ⇒ Q is equivalent to ¬P ∨ Q. This is a fundamental logical equivalence in propositional logic, called the implication law.

Now, let's analyze each option:

  1. ~ P ⇒ Q: This is equivalent to ¬(¬P) ∨ Q, which simplifies to P ∨ Q. This is not equivalent to P ⇒ Q.

  2. ((P ∧ Q) ∨ (¬P ∨ ¬Q)): This is more complex. However, it represents a formula involving a combination of both P ∧ Q and ¬P ∨ ¬Q. This is not equivalent to P ⇒ Q.

  3. P ⇒ (Q ∧ P): This simplifies to ¬P ∨ (Q ∧ P). This is not equivalent to P ⇒ Q either.

  4. P ⇒ ~Q ∧ P: This simplifies to ¬P ∨ (~Q ∧ P). Again, this is not equivalent to P ⇒ Q.

None of the given options directly match the equivalent form of P ⇒ Q (which is ¬P ∨ Q), so none of the provided options is the correct equivalent.

Here are 5 related questions for practice:

  1. What is the truth table for P ⇒ Q?
  2. How is ¬P ∨ Q derived from P ⇒ Q?
  3. What is the negation of P ⇒ Q?
  4. How does P ⇒ Q relate to logical conjunction and disjunction?
  5. Can you express P ⇒ Q in terms of a combination of AND, OR, and NOT operators?

Tip: Always remember, P ⇒ Q can be rewritten as ¬P ∨ Q for simplification purposes!
