以下是引用rushcynthia在2003-1-6 12:18:46的发言： 刚刚才看到斑竹对11题的确认,不好意思,那个问题就解决了.下面的这个我对答案也有疑义 请指教 1. Is X<0? a.) X^3 < 0 b.) X^2+X+1 =0 我认为b也对,(x^2+1)>=1,只有当x<=-1的时候,b选项的等式才会等于0,所以我认为答案是D

讨论: X^2+X+1 =0无法确定X的值,当然也就无法确定X是否小于等于零啦.

NO 44, Agree with arrymin, the Ans. should be 25pai. No.21, Agree with arrymin, the Ans. should be C(4,6). Because the question is "combination". No.51, Agree with arrymin: b
