设向量组 _(1)=((1,2,3,3))^T, (alpha )_(2)=((1,-1,2,1))^T (alpha )_(3)=((1,1,0,1))^T, (alpha )_(4)=((1,3,-2,1))^T (alpha )_(5)=((1,4,1,3))^T, 求该向量组的秩和一个极大线性无关组.

已知向量(alpha )_(1)=((1,2,1))^T, (alpha )_(2)=((2,3,a))^T, =((1,a+2,-2))^T，(alpha )

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

2.求向量组: (alpha )_(1)=((1,1,3,1))^T (alpha )_(2)=((-1,1,-1,3))^T, (alpha )_(3)=((

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

已知(alpha )_(1)=((1,1,2,2))^T, (alpha )_(2)=((1,-1,4,0))^T (alpha )_(3)=((1,0,3,1

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

8.求向量组 alpha_(1)=(1,-1,5,-1)^T, alpha_(2)=(1,1,-2,3)^T, alpha_(3)=(3,-1,8,1)^T,

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

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

一、在向量空间R^3中,求向量 alpha =((3,7,1))^T 在基-|||-(alpha )_(1)=((1,3,-1))^r (alpha )_(2)
