if p, s, and t are positive prime numbers, what is the value of p^3s^3t^3?
(1) p^3st=728
(2) t=13
OA is A
(1) p^3st=728
(2) t=13
OA is A

728 = 2^3 * 7 * 13
either s = 7 and t=13 or s=13 and t=7
it does not matter which the value of p^3s^3t^3 will remain the same.
Sufficient.
statement (2)
t=13
we dont know anything about p or s. Insufficient.
Thus, A.
