This problem illustrates the importance of establishing the base case.

(a) Let P(n) be the following: 2 + 4 + 6 + ... + 2n = n(n + 1) + 2.

Assume that for some n ∈ N, P(n) is true. Using this as your hypothesis, show that P(n + 1) is true.

(b) Is P(n) true for all n?

Definition: Let p be a prime and 0 < n then the p-exponent of n, denoted ε(n, p) is the largest number k such that pk | n. Note: for p does not divide n we have ε(n,p) = 0 Notation: Let n ∈ N+ we denote the set {p : p is prime and p | n} by Pr(n). Observe that Pr(n) ⊆ {2, 3, . . . n} so that Pr(n) is finite.
