Math Problem Statement

¬p∨(p∧(q∨(q∧p)))≡p⟹q

Solution

To determine if the given logical equivalence is true, we will simplify both sides of the equation.

The given equation is: ¬p(p(q(qp)))p    q\neg p \lor (p \land (q \lor (q \land p))) \equiv p \implies q

We'll simplify both sides step by step.

Left Side: ¬p(p(q(qp)))\neg p \lor (p \land (q \lor (q \land p)))

  1. Simplify the innermost expression (qp)(q \land p): qp=pqq \land p = p \land q (since \land is commutative)

  2. Simplify the expression (q(pq))(q \lor (p \land q)): Since pqp \land q implies qq (because pqp \land q is true only if qq is true), q(pq)=qq \lor (p \land q) = q

  3. Substitute this back into the main expression: ¬p(pq)\neg p \lor (p \land q)

  4. Distribute pp in the expression pqp \land q: pqp \land q

So the left side simplifies to: ¬p(pq)\neg p \lor (p \land q)

Right Side: p    qp \implies q

  1. Rewrite the implication using logical equivalences: p    q=¬pqp \implies q = \neg p \lor q

Comparison

Let's compare the simplified left side with the simplified right side: ¬p(pq)\neg p \lor (p \land q) ¬pq\neg p \lor q

To check if ¬p(pq)¬pq\neg p \lor (p \land q) \equiv \neg p \lor q, consider the truth table for both expressions:

ppqq¬p\neg ppqp \land q¬p(pq)\neg p \lor (p \land q)¬pq\neg p \lor q
TTFTTT
TFFFFF
FTTFTT
FFTFTT

From the truth table, we can see that the columns for ¬p(pq)\neg p \lor (p \land q) and ¬pq\neg p \lor q are identical.

Conclusion

¬p(p(q(qp)))p    q\neg p \lor (p \land (q \lor (q \land p))) \equiv p \implies q

This logical equivalence holds true.
