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:

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alpha_1, alpha_2, alpha_3, ldots线性无关，则A 向量组alpha_1, alpha_1 - alpha_2, alph

设向量组 alpha_1, alpha_2, alpha_3线性无关，判断向量组 beta_1 = alpha_1 + alpha_2、beta_2 =

已知向量组alpha_1, alpha_2, alpha_3线性无关，则A 向量组alpha_1 - alpha_2, alpha_2 - alpha_3, a

设向量组 alpha_1, alpha_2, alpha_3, alpha_4, alpha_5秩为 3，且满足 alpha_1 + alpha_3 - a

设向量组 alpha_1, alpha_2, alpha_3, alpha_4，其中 alpha_1, alpha_2, alpha_3 线性无关，则必有（）A

对于向量组alpha_1,alpha_2,ldots,alpha_m，若0alpha_1+0alpha_2+ldots+0alpha_m=0，则该向量组()。A

设向量组alpha_1, alpha_2, alpha_3, alpha_4线性无关，则()。设向量组$\alpha_1, \alpha_2, \alpha_3

设 alpha_1, alpha_2, alpha_3 是四元方程组 AX=b 的三个解向量，r(A)=3，alpha_1=(1,2,3,4)^T，alpha_

已知 alpha_1, alpha_2, alpha_3, beta, gamma 均为 4 维列向量，又 A = (alpha_1, alpha_2, alp
