Negating Formulas with Nested Quantifiers De Morgan's laws allow to rewrite the negation of a disjunction or a conjunction in a logical equivalent formula where the negation appears in front of the atomic propositions and not in front of a compound proposition: -(a A b) = ¬a V ¬6 ¬(a v b) = ¬a ^ ¬b
The solution is in two options
1 Quantifiers Consider the domain of integer numbers, and let P(x) be the statement x < x³. For each of the following formulas determine their truth values. You must justify your answers. Simply stating true or false will give you no credit, even if your answer is correct. а) Р(2) b) Р(-1) c) VxP(x) d) 3xP(x) e) 3!xP(x)
Let M(x, y) be the statement "x is a role model for y," where the domain for both x and y consists of all people in the world. Use quantifiers to express "Someone is a role model for all people."* O 3xayM(x,y) O vx3yM(x,y) O None of the mentioned O 3XVYM(x,y) O VXVYM(xy)
Check if the following statement is TRUE or FALSE. Let p(x) and g(x) be two open predicates in a universe of discourse. Is it true that (x) (p(x) v g(x)) is equivalent to (Vxp(x)) v (Vxq(x))? O True O False
Show by example that these three statements are generally false:(a) A and AT have the same nullspace.(b) A and AT have the same free variables.(c) If R is the reduced form rref(A) then RT is rref(AT ).
. If the domain consists of all animals, express the following statements in terms of quantifiers and logical connectives, where B ( x ) = x is a bear, G ( x ) = x raids garbage cans, H ( x ) = x loves honey, and T ( x ) = lives in tents. A bear lives in a tent. Bears love honey. Only bears raid garbage cans. No bear lives in a tent. Some bears do not love honey.

Alice, Bob and Cian are spies. Every spy is either a spook or an assassin. No assassin likes noise and all spooks like crowds. Cian dislikes whatever Alice likes and likes whatever Alice dislikes. Alice likes noise and crowds. 1(a) Convert the problem statement above into a set of predicate formulae. 1 (b) Convert the predicate formulae from Question 1(a) into Prenex Conjunctive Normal Form (PCNF). 1(c) Using General Resolution, determine if there a spy who is an assassin but not a spook.
discrate math
Write each of the following in terms of P(x), Q(x), R(x, y), logical connectives, and quantifiers. (a) Every integer is an odd integer. (b) The sum of any two integers is an even number. (c) There are no even prime numbers. (d) Every integer is even or a prime.
8. Give an example of a predicate P(x) and different domains so that the state- ments VxP(x) is true, VxP(x) is false, xP(x) is true, xP(x) is false.
