C. 两个向量组的秩都是5
D. 两个向量组等价
4.(判断题) 向量组满足 beta_(1)=alpha_(1), beta_(2)=alpha_(1)+alpha_(2), beta_(3)=alpha_(
7.设alpha_(1),alpha_(2),alpha_(3),beta_(1),beta_(2)均为4维列向量，矩阵A=(alpha_(1),alpha_(
4.设向量组beta_(1)=alpha_(1)+2alpha_(2)-alpha_(3),beta_(2)=alpha_(1)+2alpha_(2)+2alp
设 alpha_1, alpha_2 和 beta_1, beta_2, beta_3 是两个5维向量组，且两个向量组的秩相等，则()A. 向量组 $\alph
已知alpha_(1),alpha_(2),beta,gamma均为3维列向量，又A=(alpha_(1),alpha_(2),beta)，B=(alpha_(
(6)已知alpha_(1),alpha_(2),alpha_(3),beta,gamma均为四维列向量，又A=[alpha_(1),alpha_(2),alp
(6)已知alpha_(1),alpha_(2),alpha_(3),beta,gamma均为四维列向量，又A=[alpha_(1),alpha_(2),alp
已知beta_(1),beta_(2)是非齐次线性方程组Ax=b的两个不同的解，alpha_(1),alpha_(2)是其导出组的基础解系，k_(1),k_(2
3、已知beta_(1)、beta_(2)是非齐次线性方程组Ax=b的两个不同解，alpha_(1)、alpha_(2)是其对应的齐次线性方程组Ax=0的一个基
3.判断题设向量beta可由向量组alpha_(1),alpha_(2),alpha_(3),alpha_(4)线性表示，但不能由alpha_(1),alpha
