ewrite the following proposition as unambiguous English sentences. The relevant redicates are defined as follows: Again, let's let P be a set of all people a. A(x) means "x is teaching the Al course" b. T(x) means "x is taking Al course" c. F(x) means "x has a twitter account." d. C(x) means "x likes to read."
Propositions and quantifiers Let x, y ∈ {2, 3, 4}.

Consider the wffs:φ1 ≡ p1 → (p2 → (p3 → p4))φ2 ≡ (p1 ∧ p2 ∧ p3) → p4(a) Technically speaking, neither φ1 nor φ2 is well-formed since neither is allowed by the formal syntaxof propositional logic. Correct them. Note, however, that we will freely make such trivial ’errors’ throughout this semester (as do most such courses).(b) Use truth tables (in the form defined in this course) to show that φ1 ↔ φ2.(c) After internalizing an intuitive understanding of this equality, propose an extension of it to n atoms.(d) State the number of rows in a truth table for proving the extension

Please answer the following question in depth with full detail. Consider the 8-puzzle that we discussed in class. Suppose we define a new heuristic function h3 which is the average of h1 and h2, and another heuristic function h4 which is the sum of h1 and h2. That is, for every state s ∈ S: h3(s) =h1(s) + h2(s) 2 h4(s) =h1(s) + h2(s) where h1 and h2 are defined as “the number of misplaced tiles”, and “the sum of the distances of the tiles from their goal positions”, respectively. Are h3 and h4 admissible? If admissible, compare their dominance with respect to h1 and h2, if not, provide a counterexample, i.e. a puzzle configuration where dominance does not hold.

The relevant predicates are defined as follows: Again, let’s let P be a set of all people A(x) means “x is teaching the AI course” T(x) means “x is taking AI course” F(x) means “x has a twitter account.” C(x) means “x likes to read.” For example, the proposition ∃x { P [A(x)∧ C(x)]} could be translated as “There is a person who is teaching and likes to read” P [T(x) → (F(x) C(x))] ?
