Given:
The matrix is
.
To find:
The determinant of given matrix, i.e,
.
Solution:
If a matrix is A of order
, then the value of the determinant of that matrix is equal to the element of that matrix.
For example: Let A be the matrix of order
.
![A=[a]](https://tex.z-dn.net/?f=A%3D%5Ba%5D)
Then,

The given matrix is
. So, the determinant of given matrix, i.e,
, is

Therefore, the value of determinant of given matrix is -8.
