WebMath Discrete Math Question Identify the error or errors in this argument that supposedly shows that if ∀x (P (x) ∨ Q (x)) is true then ∀xP (x) ∨ ∀xQ (x) is true. 1. ∀x (P (x) ∨ Q (x)) Premise. 2. P (c) ∨ Q (c) Universal instantiation from (1) 3. P (c) Simplification from (2) 4. ∀xP (x) Universal generalization from (3) 5. Web1. ∀x∃y [x is married to y] 2. ∃y∀x [x is married to y] I'm doubtful about the answer to this example. Also, some explanation about ordering of ∃ and ∀ operators would be appreciated. logic discrete-mathematics Share Improve this question Follow asked Oct 21, 2015 at 17:15 Arpit Quickgun Arora 39 1 1 5 1

WebSuppose that∀xP(x) ⋀∀xQ(x) is true. It follows that ∀xP(x) is true, and that ∀xQ(x) is true. Hence, for each element a in the domain P(a) is true, and Q(a) is true. Hence P(a)⋀Q(a) is true for each element a in the domain. Therefore, by definition, ∀x(P(x)⋀Q(x)) is true. 10 WebFundamental theorem of arithmetic.
