When 81 is divided by the cube of positive integer z, the remainder is 17. Which of the following could be the value of z?
I.	2
II.	4
III.	8 Choose the correct choice:
A) I only B) II only C) III only D) I and II only E) I, II and III
81 divided by z^3 leaves a remainder of 17.   81 = q * 2^3 + 17   64 = q+z^3   Then I tried answer possibilities of 2, 4 and 8.   Only 2^3 = 64 fulfills the equation and yields a remainder of 17.   ANSWER:II only
