a Problem 1. Suppose A denotes the string ((-(p+ (qV 1)))

a Problem 1. Suppose A denotes the string ((-(p+ (qV 1))) = (q^r)) over V. (a) Use the formula-calculation method to show that A is a (well-formed) for- mula. (b) Suppose v is a state such that v(p) v(q) t and v(r) = f. What is the - value of v(A)? Show your work. = = = Problem 2. Use induction on formulae to prove that the complexity of a formula is equal to the number of its right brackets
