We have to get the value of integer k.M7MBA wrote:What is the value of the integer k?

Let's take each statement one by one.
(1) k + 3 > 0
=> k > -3; k can be -2, -1, 0, 1, ... there is no unique value. Insufficient.
(2) k^4 ≤ 0
The only eligible value for k is 0 as we see that 0^4 = 0 ≤ 0.
Plugging in the value -1 or +1 will not help.
Say k = ±1; we have k^4 = (±1)^4 = 1 ≥ 0. Invalid value.
The correct answer: B
Hope this helps!
