Exercises for Section 2.6 A. Use truth tables to show that the following statements are logically equivalent. 1. PA(QVR) =(PAQ)V(PAR) 5. ~(PVQ VR) = (~P)A(~Q)A(~R) 2. PV(QAR) = (PVQ)A(PVR) 6. ~ (PAQAR) = (~P)V(~Q) V(~R) 3. P = Q=(~P)vQ 7. P = Q = (PA ~ Q) = (Q~ ~Q) 4. ~ (P VQ) = (~P) A(~Q) 8. ~ P + Q = ( P = ~ Q) A(~Q= P) B. Decide whether or not the following pairs of statements are logically equivalent. 9. PAQ and ~ (~ Pv ~ Q) 12. ~ (P = Q) and PA ~Q 10. (P = Q)VR and ~((PA ~Q)A ~R) 13. Pv(QAR) and (PVQ)AR 11. (~P) A(P = Q) and ~ (Q = P) 14. PA(Qv ~ Q) and (~ P) = (QA ~Q)
