若向量组(alpha )_(1)=((1,1,1))^T (alpha )_(2)=((0,1,1))^T (alpha )_(3)=((0,0,1))^T能由向量组(alpha )_(1)=((1,1,1))^T (alpha )_(2)=((0,1,1))^T (alpha )_(3)=((0,0,1))^T线性表示，则向量组(alpha )_(1)=((1,1,1))^T (alpha )_(2)=((0,1,1))^T (alpha )_(3)=((0,0,1))^T的秩为（ ）。A.3 B.2C.1 D.无法确定

设向量组 (alpha )_(1)=((0,1,1))^T, (alpha )_(2)=((1,0,1))^T (alpha )_(3)=((2,1,0))^T

设向量组(alpha )_(1)=((1,0,1))^T，(alpha )_(1)=((1,0,1))^T，(alpha )_(1)=((1,0,1))^T不能

5、设有向量组 (alpha )_(1)=((1,1,2,3))^T , (alpha )_(2)=((1,-1,1,1))^T , (alpha )_(3)=

设向量(alpha )_(1)=((1,1,-1))^T (alpha )_(2)=((0,2,1))^T,(alpha )_(1)=((1,1,-1))^T

设向量组 _(1)=((1,2,3,3))^T, (alpha )_(2)=((1,-1,2,1))^T (alpha )_(3)=((1,1,0,1))^T,

若向量组(alpha )_(1),(alpha )_(2),(alpha )_(3)线性无关，则向量组(alpha )_(1),(alpha )_(2),(al

设向量组 alpha_1 = (1,1,1), alpha_2 = (0,1,2), alpha_3 = (1,0,-1)，那么该向量组的秩为:A. 3B

设向量组 alpha_1 = (1,1,1), alpha_2 = (0,1,2), alpha_3 = (1,0,-1)，那么该向量组的秩为:A. 2B

已知向量组A: overrightarrow ({alpha )_(1)}=(0,1,2,3)T overrightarrow ({alpha )_(2)}=(

已知向量组I: (alpha )_(1)=((1,1,4))^T, (alpha )_(2)=((1,0,4))^T, _(3)=((1,2,{a)^2+3)}
