Show that the following are not logically equivalent by finding a counterexample:
(p^q) →r and
(db) V (d←d)
Show that the following is not a contradiction by finding a counterexample:
(pV-q) AqA (pv¬q Vr)
3.
Here is a purported proof that (pq) ^ (q → p) = F:
(db) v (bd) = (db) v (bd)
=(qVp) A (g→p)
= (¬¬q V ¬p) ^ (q→ p)
(db) V (db) =
=¬(a→p)^(a→p)
= (gp) ^¬(a → p)
=F
(a) Show that (pq) ^ (q→p) and F are not logically equivalent by finding a counterex-
ample.
(b) Identify the error(s) in this proof and justify why they are errors. Justify the other steps
with their corresponding laws of propositional logic.

- 4. 5. 6. Prove that p (gp) is a tautology using the laws of propositional logic. Prove that p((pVq) → q) is a tautology using the laws of propositional logic. Let us say a natural number n is ok if there are two natural numbers whose sum is n and whose product is n. (Convention: the natural numbers consist of 0, 1, 2,...) (a) Give a logical expression that means "n is ok". (b) Show that 0 and 4 are both ok. (c) Give a logical expression that means "every natural number is ok". (d) Give a logical expression that means "it is not the case that every number is ok". Push the negations into the expression as far as possible.arrow_forward7.
