3) For any positive integer n, the length of n is defined as the number of prime factors whose product is n. For example, the length of 75 is 3, since 75 = 3 * 5 * 5. How many two-digit positive integers have length 6?

a)None

b)One

c)Two

d)Three

e)Four

Start with 2 to check the lowest number with length 6,

2*2*2*2*2*2 = 64

substitute one two with 3, and product becomes 96

substitute two 1s with two 3s, prod becomes more than 2 digits

answer = 2 numbers (64 and 96)
