3. Let A c R X be a square matrix. Suppose we do the following elementary row operations in the given order: . Multiply row three by 2. . Replace row two with the sum of rows one and two. . Swap rows three and four. . Divide row four by 6. At the completion of this, we have an identity matrix. (a) What is the determinant of A? (b) What is the inverse of A? (c) Write A as a product of elementary matrices
