1. Using logic simplification determine if the following proposition is a tautology. Show all the steps. DO NOT USE TRUTH TABLE.
((p q) p ) q
2. Using logic simplification determine if the following proposition is a contradiction. Show all the steps. DO NOT USE TRUTH TABLE.
p (pq) q
3. Prove that p q (p q) (pq).
Hint. Obtain a logic expression of the left hand term taking the TRUE logic from its truth table. Then simplify the expression.
If M: p q and N: q p, can you say if MN will be a tautology? Why or why not? Justify your answer.
