Answer 1

hi dude

Answer:

Properties of determinants

1. Interchange two rows or cols changes the sign: -> -1 * det(A) ...
2. transpose -> det (A) unchanged. ...
3. multiply row * k -> k * det(A) ...
4. multiply matrix * k -> k^2 * det(A) ...
5. det (A B) -> det(A) * det(B) ...
6. proportional rows or columns -> det() == 0. ...
7. Add multiple of one row to another -> det unchanged. ...
8. Geometric interpretation.

hope my ans helps u!!
