Compute the determinant of the matrix A, below, by using row operations to transform A to an upper-triangular matrix B. Then express the determinant of A as a multiple k of the determinant of B, and use this to compute the determinant of A. 278-1 A = 6 29 18 2 274 2 10 59 38 1 000 B=000 10 0 0 det(A) = k-det(B) = 0.0 = 0
