You don't know if k and p have common prime factors, so even both data together may not be sufficient. hence Egrandh01 wrote:If m=kp, where k and m are different positive integers,
then does m have more than 5 prime factors?
1) k has 5 different prime factors
2) p has 5 different prime factors
OA IS E

If x,y, and n are positive integers, is (x/y)^n > 1000 1) x=y^3 and n>y 2) x>5y and n> x oa is B Put Statement 1 in the equation => y^2n, n>y(that means n can be 2,3,4...) It's not necessarily >1000, so it's insufficient. So x/y is great than or at least 6 and 6^6 >100, so it's sufficient. So the a...
