Some of the following arguments are valid by universal modus ponens or universal modus tollens; others are invalid and exhibit the converse or the inverse error. State which are valid and which are invalid. Justify your answers. c) If a product of two numbers is 0, then at least one of the numbers is 0. I pick a number x such that neither (2x + 1) nor (x − 7) equals 0. Therefore, the product (2x + 1)(x − 7)...

Remember that p and q can star with other operators (even other horseshoes) within. It does not matter whethe o previousp listing the conditional's antecedent.

I just need help with detailed explanations for b and c
Use the rules of inference and the laws of propositional logic to prove that each argument is valid. Number each line of your argument and label each line of your proof "Hypothesis" or with the name of the rule of inference used at that line. If a rule of inference is used, then include the numbers of the previous lines to which the rule is applied. (a) p q...
