i- (8 points) Find the output of each of these 2 combinatorial circuits. j- (12 points) Show that each of these conditional statements is a tautology by using truth tables. (-p A (p V q)] q [p ^ (p q)] q (q ^ (p q)) -p k- (6 points) Show that each conditional statement in the previous exercise is a tautology without using truth tables. l- (6 points) Write a proposition equivalent to p V q that uses only ,A
