Let A be a 3x3 invertible matrix. The reduced row-echelon form of A is obtained by performing the following three elementary row operations in order: () First multiply row 2 by-2. () Then add 2 times row 3 to row 2. (ii) Then finally interchange rows I and 3. Then what is det(A)? det(A) = 0 Let A be a 3x3 invertible matrix.
