Problem of the Week #4 1. An integer bis said to be divisible by an integer a 0, in symbols ab. if there exists some integer c such that b = ac. In other words, b is divisible by a if a goes into b with no remainder. For example, 30 is divisible by 5 (in symbols, 5 30 ) because 30 = 5 x 6. Problem of the Week: The following integers are all divisible by 31: 28272, 27683,...

1. An integer n is divisible by 9 if the sum of its digits is divisible by 9. Develop a program to determine whether or not the following numbers are divisible by 9: n= 154368 n 621594 n-123456 2. A number is said to be perfect if the sum of its divisors (except for itself) is equal to itself. For example, 6 is a perfect number because the sum of...
Show that the given argument is invalid by giving values for the predicates P and Q over the domain {a, b}. (a) ∀x (P(x) → Q(x)) ∃x ¬P(x) ∴ ∃x ¬Q(x) (b) ∃x (P(x) ∨ Q(x)) ∃x ¬Q(x) ∴ ∃x P(x)
