Prove that there is an equivalent set of properties of determinants for column operations as there are for row operations. Complete the proof for each property on 3x3 matrices. [Hint: you may find using elementary matrices to be of help. To perform column operations with elementary matrices, multiply on the right instead of the left.] a. Exchanging two rows of a matrix changes the sign of the determinant. b. Adding two rows of a matrix does not change the value of the determinant. c. Multiplying one row of a matrix by the scalar k changes the value of the determinant by k.
