So the determinant is d = 1*1*8 = 8. So you are correct. Answer by stanbon(57962)   (Show Source): You can put this solution on YOUR website!Yes, the determinant is 8. Cheers, Stan H. Answer by solver91311(17077)   (Show Source): You can put this solution on YOUR website! Yes, the Determinant is 8. Write back and I'll send you a document that shows you the Gauss-Jordan Inverse.
