Approach:
In linear algebra, the determinant is a scalar value that can be computed from the elements of a square matrix and ecodes certain properties of the linear transformation described by the matrix.
Calculation:
Given is the matrix A=[1234a212343212343212a4321]
The row echelon form of given matrix after applying row transformation,
=[a43212123432123432121234a] R1  R5
=[a43210a  8a2a  6a3a  4a4a  2a32123432121234a] R2  R2  2a  R1
=[a43210a  8a2a  6a3a  4a4a  2a02a  12aa  9a2a  6a3a  3a432121234a] R3  R3  3a  R1
=[a43210a  8a2a  6a3a  4a4a  2a02a  12aa  9a2a  6a3a  3a03a  16a2a  12aa  8a2a  4a1234a] R4  R4  4a  R1
