设n维向量a1,a2.aS的秩为r
则A.向量组中任意r-1个向量都线性无关 B.向量组中任意r个向量均线性无关
C.向量组中任意r+1个向量军线性无关 D,向量组中的向量个数必大于r

解答
选B
B包含了A,
C秩是向量组里极大线性无关组个数
Dr个也行
推荐
- 设n维向量组a1,a2,...,as的秩等于r,如果r=s,则任何n维向量都可用a1,a2,...
- 设a1,a2,^,a,为n维向量组,且秩 （a1,a2,^,a）=r,则（）
- 设n维向量组 a1,a2...,as,as+1(s
- 刘老师,若n维向量组a1,a2,...,am的秩为R 则R是≤m 还是R＜m?
- 设有n维向量组A:a1,a2;向量组B:a1,a2,a3;向量组C:a1,a2,a4的秩为R（A）=R（B）=2.R（C）=3,
- to his surprise ,this time there were six .
- 用形容词的适当形式填空 In this country it's very ------(cold)in November,and it's much
- he stepped into the room quietly without being noticed.后面的without being noticed是什么意思?
