1. Use elementary row or column operations to evaluate the determinant. Show all work. | 0 -3 8 2 8 1 -1 6 -4 6 0 9 -7 0 0 14 | 2. Without performing any calculations, explain in words why the following is true. |2 1 0 4 1 0 3 2 0 4 2 0 -1 8 3 -2 |=0 3. Let A and B be square matrices of order 3 such that |A|= -2 and |B|= 5. Find (a)|BA|,(b) |B^4|,(c) |2A|, (d) (AB)^T|, and (e) |B^-1|.
