D. $\lambda=1$ 或 $\lambda=-2$
3.设向量组alpha_(1)=(lambda+3,lambda,3lambda+3,)^T,alpha_(2)=(1,1-lambda,lambda,)^T,
已知向量组 alpha_(1)=(t,2,1)^T,alpha_(2)=(2,t,0)^T,alpha_(3)=(1,-1,1)^T线性相关，则t的值为（）A.
设alpha_(1),alpha_(2),alpha_(3),alpha_(4)线性无关，且alpha_(1),alpha_(2),alpha_(3),alph
设alpha_(1),alpha_(2),alpha_(3),alpha_(4)线性无关，且alpha_(1),alpha_(2),alpha_(3),alph
已知向量组alpha_(1),alpha_(2),alpha_(3)线性无关，若alpha_(1)+alpha_(2),alpha_(2)+alpha_(3),
(9)设向量组alpha_(1)=(1,3,6,2)^T,alpha_(2)=(2,1,2,-1)^T,alpha_(3)=(1,-1,a,-2)^T线性相关，
13.单选题若alpha_(1)=(1-1 2),alpha_(2)=(-2 1 0),alpha_(3)=(-1 0 t)线性相关,则()A. t=-2B.
1.单选题已知向量组alpha_(1),alpha_(2),alpha_(3)线性无关，则A. 向量组$\alpha_{1},\alpha_{1}-\alpha
2.判断向量组alpha_(1)=(1,2,-1,3)^T, alpha_(2)=(2,1,0,-1)^T, alpha_(3)=(3,3,-1,2)^T是否线
2.[判断题]非零向量alpha_(1),alpha_(2)线性相关，则存在k使得alpha_(1)=kalpha_(2)A. 对B. 错
