What is the value of the integer k?
(1) k + 3 > 0
k > -3
k can anything from -3 to positive infinity; k ={-3,-2,-1,0,1,2,3,4,5,....99...13456.... infinity}
INSUFFICIENT
(2) \(k^4\) \(<= 0\)
Raising any number to an even power removes the possibility of getting a negative number in the output.
so the expression become \(k^4=0\)
therefore k is also 0
SUFFICIENT
ANSWER IS B
