) Show that ∀xP(x) ∧ ∃xQ(x) is logically equivalent to ∀x∃y(P(x) ∧ P(y)) The quantifiers have the same non empty domain. I know that to prove a proposition is logically equivalent to another one, I have to show that ∀xP(x) ∧ ∃xQ(x) ↔ ∀x∃y(P(x) ∧ P(y)) Which means I have to prove that (∀xP(x) ∧ ∃xQ(x)) → ∀x∃y(P(x) ∧ P(y)) ∧ ∀x∃y(P(x) ∧ P(y)) → (∀xP(x) ∧ ∃xQ(x)) I don't know the answer, so I saw the textbook answer. It says (1) Suppose that ∀xP(x) ∧ ∃xQ(x) is true. Then P(x) is true for all x and there is an element y for which Q(y) is true. I get this part. Because P(x) ∧ Q(x) is true for all x and there is a y for which Q(y) is true, ∀x∃y(P(x) ∧ P(y)) is true. Emm... I think ∀x∃y(P(x) ∧ P(y)) is true because ∀x only affects P(x) and ∃y only affects P(y) since their alphabets are different. So, it has the exact same meaning as ∀xP(x) ∧ ∃yQ(y). And since the domains are the same, ∀xP(x) ∧ ∃yQ(y) is actually equal to ∀xP(x) ∧ ∃xQ(x). But the textbook states that "P(x) ∧ Q(x) is…

prove the equivalence of the schemata:~(~(p • ~ q ) • ~ ( ~ p• q)) equal to ~(p • q) • ~(~p • ~q)
Let P(x) and Q(x) be relations, with x a variable from a given domain of discourse U. The Axiom of the Hilbert deductive system for first-order logic applied below is "Axiom 1,2,3,4,5" ? ⊢ ∀x P(x) → (∃x Q(x) → ∀x P(x)) Consider the steps given below of a proof in the Hilbert deductive system and determine the reason that justifies each. ∀x A(x) ⊢ ∀x A(x) "?"∀x A(x) ⊢ ∀x A(x) → A(a) " ?"∀x A(x) ⊢ A(a) " ?"
Determine whether the following proposition is a tautology. ((¬p ᴠ ¬q) (p ᴧ q ᴧ r)) (pᴧ q)
Simplify the given proposition using Logical Equivalence rules and determine if it is a tautology, contradiction orcontingency. Do not forget to indicate rule/s applied in each step. 1. ¬(q ⊕ p) → ¬(p ∧ q) 2. (¬p ∧ r) ⊕ (p ∨ q)
2) (L2) Prove using laws of logic that the conditional proposition (p ∧ q) → r is equivalent to (p ∧ ¬ r) →¬ q. 3) (L3) Show that the converse of a conditional proposition p: q → r is equivalent to the inverse of proposition p using a truth table. 4.1) (L4) Show whether ((p ∧ (p→q)) ↔ ¬p) is a tautology or not. Use a truth table and be specific about which row(s)/column(s) of the truth table justify your answer. 4.2) (L4) Give truth values for the propositional variables that cause the two expressions to have different truth values. For example, given p ∨ q and p ⊕ q, the correct answer would be p = q = T, because when p and q are both true, p ∨ q is true but p ⊕ q is false. Note that there may be more than one correct answer. r ∧ (p ∨ q) (r ∧ p) ∨ q
