There's no need to use distribution since p∨(¬q∨r)≡p∨¬q∨r due to associativity of ∨, and by commutativity of ∨, that gives us ...

01.10.2020 · Prove without using truth tables: ( ( ( p ∨ r) ∧ q) ∨ ( p ∨ r)) ∧ ( ¬ p ∨ r) ⇔ r. I tried but I always get stuck when applying like 4 laws, and i don't even know if i using them correctly, i think is the ¬p that is given me problems here, please help. This its what i have so far.

5.. Use De Morgan's Laws, and any other logical equivalence facts you know to simplify the following statements. Show all your steps. Your final statements should have negations only appear directly next to the sentence variables or predicates (\(p\text{,}\) \(q\text{,}\) etc.), and no double negations.

3-2. SUBSTITUTION OF LOGICAL EQUIVALENTS AND SOME MORE LAWS We can't do much with our laws of logical equivalence without using a very simple fact, which our next example illustrates. Consider '--A' is logically equivalent to 'A'. This makes us think that (1) is logically equivalent to (2) AVB. This is right.
