Statement 1 you can toss pretty quickly. k > -3, so k could be -2 or -1, etc.Vincen wrote:What is the value of integer k?
(1) k + 3 > 0
(2) k^4 ≤ 0
OA is B.
How can I determine the value of k? Please help.
The key to statement 2 is recognizing that if you take a base and raise it to an EVEN exponent, the value can never be negative. So if k^4 is less than or equal to 0, and it can't be less than 0, then it has to be equal to 0. Thus k = 0. Statement 2 alone is sufficient. The answer is B
