1.计算行列式-|||-a b b b-|||-b a b b-|||-b b a b-|||-b b b a

a+b b a . a+b b a a+b a . (aneq b)-|||-b-|||-a+b

因为-B=(Acup B)-B,所以-B=(Acup B)-B.因为,所以.

设A,B均为n阶方阵，则必有（ ）A, |A+B|=|A|+|B|A, |A+B|=|A|+|B|A, |A+B|=|A|+|B|A, |A+B|=|A|

设A、B、C是任意三个随机事件，则下列命题正确的是( )(Acup B)-B=A-B(Acup B)-B=A-B(Acup B)-B=A-B(Acup B

设a＞b＞0，证明：(a-b)/(a)＜ln(a)/(b)＜(a-b)/(b)．设a＞b＞0，证明：$\frac{a-b}{a}$＜ln$\frac{a}{b}
