How are these two logical expressions equivalent? (Please show the steps with the logical equivalence names you used)

3. Here is a list of five propositional forms and three circuits. This list contains four pairs of logically equivalent entries (we will say a circuit is equivalent to a propositional form if the propositional form describes the value of the circuit's output for all possible combinations of input values). For instance, maybe A = B, C = D, E = F and G = H). First determine the four pairs, and then prove for each pair that one element of the pair jo logically equivalent to the other one. (A) ~((p+q) V (qHr)) P)) DJ (~p^q^~r) v (p^~q1r) output Ao BA output mo output
