Math Problem Statement

) If p→ (p→ q ) is false, then find the truth values of p and q.

Solution

To solve this, we need to analyze the given expression p(pq)p \to (p \to q) and determine when it is false.

  1. First, recall the truth table for the implication pqp \to q:
    • pqp \to q is false only when pp is true and qq is false.
    • Otherwise, pqp \to q is true.

Now, we want p(pq)p \to (p \to q) to be false. This means:

  • pp must be true (since p(pq)p \to (p \to q) is false only when the antecedent is true and the consequent is false).
  • (pq)(p \to q) must be false for the entire implication to be false.

For (pq)(p \to q) to be false:

  • pp must be true and qq must be false.

Thus, the truth values are:

  • p=truep = \text{true}
  • q=falseq = \text{false}

Conclusion:

For p(pq)p \to (p \to q) to be false, pp must be true and qq must be false.

Here are 5 related questions:

  1. What is the truth table for pqp \to q?
  2. How does double implication (biconditional) differ from implication?
  3. Can an implication be false when the consequent is true?
  4. How would you express p(pq)p \to (p \to q) using logical operators like AND and OR?
  5. In which logical systems does implication behave differently?

Tip: When analyzing implications, focus on when the antecedent is true and the consequent is false—this is the only time the implication is false!
