Given p, q and r is the praphot praphot ~ [(Λ p q) → (~ q V r)] equivalence with the praphot in the following text.1. p Λ ~(q → r) 2. ~q V (~p Λ r)3. ~(p Λ q) Λ (q Λ r) 4. ~(p Λ q)→(q Λ ~r)
The p, q, r a p p ~ [(p Λ q) → (~ q V r)] is equivalent to the proposition in any of the following one. P ~ lambda (Q → R) 2. Q ~ V (lambda R ~ P) 3. ~ (lambda P Q) lambda (lambda Q R) 4. ~ (lambda P Q) → (Q lambda ~ R).
The p q R, and a proposition proposition ~ [(P Λ q) - > (~ Q V R)] equivalent to proposition in which of the following 1. P Λ ~ (Q - > R) 2. ~ Q V (~ p. Λ R) 3. ~ (P Λ q) Λ (Q Λ R) 4. ~ (P Λ q) - > (Q Λ ~ r).
