Question

Can we interchange any two rows or any two column of matrix? Will there be any change in its value? ​

Answer 1

Answer:

If two rows (columns) in A are equal then det(A)=0. If we add a row (column) of A multiplied by a scalar k to another row (column) of A, then the determinant will not change. If we swap two rows (columns) in A, the determinant will change its sign.

Answer 2

Answer :

If two rows (columns) in A are equal then det(A)=0. If we add a row (column) of A multiplied by a scalar k to another row (column) of A, then the determinant will not change. If we swap two rows (columns) in A, the determinant will change its sign. det(A)=det(AT).
