If s, t, and u are distinct positive prime numbers, then (s^3)(t)(u) has how many different positive factors greater than 1? Pick:
A) a. 8
B) b. 9
C) c. 12
D) d. 7
E) e. 27
Let Number is (s^3)(t)(u) = (1^3)(5)(6) = 30   We can write 30 as product of two numbers in following ways   1*30   2*15   3*10   5*6   4 cases = 4*2 i.e. 8 factors (including 1)   Factors greater than 1 = 7   Answer: Option d. 7
