The order of a matrix is shown by: |
- A.
- B. number of columns + number of rows
- C. number of rows × number of columns
- D. number of columns - number of rows
|

|
- A. ab - cd = 0
- B. ac - bd = 0
- C. ad - bc = 1
- D. ad - bc = 0

- A. scalarmatrix
- B. diagonalmatrix
- C. lower triangularmatrix
- D. uppertriangularmatrix

If the matrices A & B have the orders 2×3 and 5×2 then order BA is: |
- A. 3×5
- B. 5×2
- C. 2×2
- D. none
|
| 8 |
If AB = BA = I, then A and B are: |
