设 alpha_1, alpha_2, alpha_3 线性无关，则，当 k, l 满足 ()条件的时候向量组 lalpha_2 - alpha_1, malpha_3 - alpha_2, alpha_1 - alpha_2 也线性无关。

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

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，其中 alpha_1, alpha_2, alpha_3 线性无关，则必有（）A

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 =

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

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

向量组 alpha_2, alpha_4, alpha_5 线性无关，则整体向量组 alpha_1, alpha_2, alpha_3, alpha_4, al

beta_1 = alpha_1, beta_2 = alpha_1 + alpha_2, beta_3 = alpha_1 + alpha_2 + 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

已知: alpha_1, alpha_2, alpha_3 线性无关，beta_1 = 2alpha_2 - alpha_3，beta_2 = -alpha_1
