True or false? 7. If A and B are row equivalent then det(A) = det(B).

False

Reason

Any nonsingular matrix is row equivalent to the

identity matrix - but it's certainly not true that any nonsingular matrix

has determinant equal to one.

det(A)=ad-cb

let B is matrics obtained from A by operation    

 !=det(A
