If x is the product of the positive integers from 1 to 8, inclusive, and if i, k, m, and p are positive integers such that x=2^i∗3^k∗5^m∗7^p, then i + k + m + p =  Answers
A) 4 B) 7 C) 8 D) 11 E) 12
Here the idea is to go expressing each factor from one to eight, decomposed into its primes:   1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 = 1 * 2 * 3 *(2*2) * 5 +(2*3) * 7 *(2*2*2) = 2 ^ 7 * 3 ^ 2 * 5 ^ 1 * 7 ^ 1   Then   i = 7   k = 2   m = 1   p = 1   i + k + m + p = 11   Correct answer 11
