Prove that the following matrix are singular:
`[(3,2,1),(0,4,5),(3,6,6)]`

Are the following matrices non-singular ? A=[[1,2,3],[2,4,6],[1,4,5]] , B=[[1,2,3],[2,4,6],[3,5,9]]

Check whether the following matrix is invertible or not. [[1,2,3],[3,4,5],[4,6,8]]

Wherever possible write each of the following as a single matrix. (i) [{:(,1,2),(,3,4):}]+[{:(,-1,-2),(,1,-7):}] (ii) [{:(,2,3,4),(,5,6,7):}]-[{:(,0,2,3),(,6,-1,0):}] (iii) [{:(,0,1,2),(,4,6,7):}]+[{:(,3,4),(,6,8):}]

Identify the singular and non-singular matrices: [(1,2,3),(4,5,6),(7,8,9)]

Using elementary transformation, find the inverse of the following matrix [{:(2,5,3),(3,4,1),(1,6,2):}]

Find the Inverse of the following matrix by using Row Transformations: [[1,2,3],[2,4,5],[3,5,6]] .
