QUESTION:

Use propositional logic to prove the validity of the arguments in Exercises 2533. These will become additional derivation rules for propositional logic, summarized in Table 1.14.P ` (Q ~ R) S (P ` Q) ~ (P ` R) (Hint: First rewrite the conclusion.)

ANSWER:

Step 1 of 2

The validity of the argument can be proved by using the inference rules. It is proved by using the sequence of the hypothesis in the propositional logic.
