 1. `[[8,-6,2],[-6,7,-4],[2,-4,3]]`
2. `[[6,-2,2],[-2,3,-1],[2,-1,3]]`
3. `[[3,2,4],[2,0,2],[4,2,3]]`
4. `[[1,1,1],[-1,-3,-3],[2,4,4]]`
5. `[[2,3],[4,10]]`
6. `[[5,1],[4,2]]`

Example1. Find value of determinant using properties of determinants ...
`[[201,210,220],[151,155,140],[50,55,80]]`Solution:| `A=` | | 201 | 210 | 220 | | | 151 | 155 | 140 | | | 50 | 55 | 80 | |
|
Now, `R_1 = R_1 - R_2` | `=` | | 50 | 55 | 80 | | | 151 | 155 | 140 | | | 50 | 55 | 80 | |
|
Here `R_3 = R_1`, So value of the determinant is 0 `=0`
