Hi everyone,
Had a little trouble with this question. What's the shortcut for finding the product of all integers from x to y? a brief explanation would be appreciated. thanks!
FYI, I pulled this directly from Zuleron's gmat prep document. The answer is E
104) For every positive even integer n, the function h(n) is defined to be the product of all even integers from 2 to n inclusive. If p is the smallest prime factor of h(100) + 1, then p is between
a. 2 and 10
b. 10 and 20
c. 20 and 30
d. 30 and 40
e. > 40
