Question: Let p , q and r be propositional variables. Prove the following logical equivalence ( p - > q ) ( p - > r

Let p,q and r be propositional variables. Prove the following logical equivalence
(p -> q)(p -> r)(qr)-> p
(1)...using a truth table. In your truth table, include at least 3 intermediate steps.
(2)...using the laws of logic. You must use only one law per step, and name the law you are using at each step.
