设alpha=(3,-1,0,2)^T，beta=(3,1,-1,4)^T，若向量gamma满足2alpha+gamma=3beta，则gamma=().

向量 alpha = ((1)/(2) ), beta = ((3)/(2) ), 向量 gamma 满足 2gamma + alpha = 3beta, 那么

设三阶矩阵 =(alpha ,gamma 1,(y)_(2)), =(beta ,gamma 1,(gamma )_(2))其中 =(alpha ,gamma

设 A 与 B 为 4 阶方阵，alpha, beta, gamma_2, gamma_3, gamma_4 均为 4 维列向量，A = (alpha, gam

已知alpha_(1),alpha_(2),beta,gamma均为3维列向量，又A=(alpha_(1),alpha_(2),beta)，B=(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
