To compute |kA|, you need to know that everytime you scale a row of a matrix, it scales the determinant. There are 3 rows in A, so kA is A with 3 rows scaled by k, which multiplies the determinant of A by k^3. In general if A is n x n, then |kA|=k^n |A|. Comment.1 Answer. The determinant of a matrix can be evaluated by expanding along a row or a column of the matrix.
