判断下列向量组是线性相关还是线性无关.如果线性相关，试找出其中一个向量，使得它可以由其余向量线性表出，并且写出它的一种表达式：[tex=18.0x3.643]SnEN0b3+0/UDsLx8pK3eHJNv7KfuVYeZSbYEyInVwLq35CYcibebkkRFFBD1yH6lgPg6pNlIQz9qMxo2BcHt5ZAl3OcHznSnjubVRp5oPbuH+kKWcyA6vDaiFvFBOR2EEY8nWibOIwzn7Bm4nxHLiuKfs4CdoIHANFZKuo0EtpRdABWgEBSoKl0bJx1cKF72HVwENdvsc3mdVstsJgQbMM77Yl2vPl58Vtib65TwtyZdam9INXFidGCYEvqN0oduL0LC/IWt54tIi1zOkbTliw==[/tex]
举一反三
- 下列向量组中，（ ）是线性无关向量组。 A: (1, 1, 0), (0, 2, 0), (0, 0, 3) B: (1, 2), (3, 0), (5, 1) C: (2, 6, 0), (3, 9, 0), (0, 0, 2) D: (1, 2), (--3, 0), (5, 1)
- >>>x= [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9]>>>print(x.sort()) 语句运行结果正确的是( )。 A: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] B: [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9] C: [10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0] D: ['2', '4', '0', '6', '10', '7', '8', '3', '9', '1', '5']
