Question

The interchange of any two rows (or columns) of the determinant changes its sign.

Answer 1

Answer:

det(A)=det(AT)

Step-by-step explanation:

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).

Answer 2

Answer:

column transformation
