1 [20 pts (5, 10, 5)]: Logic Circuits 1. Draw the circuit corresponding to the following expression. (Do not simplify your expression or the corresponding circuit.) ((p q r) (q r)) 2. Now use the laws of logical equivalence to simplify your expression so that negations, where ever they occur, appear before single variables only. Show every step and state the Law of Logical Equivalence you are using at each step. 3. Draw the simplified circuit corresponding
