    4ln(8x-1) + 4 = -4

          4ln(8x-1) = -8

            ln(8x-1) = -2

                 8x-1 = e⁻²

                 8x-1 = 1/e²

                    8x = 1 + 1/e²

                    8x = (e²+1)/e²

                              e²+1

                       x = ———   or   ⅛(1 + 1/e² )

                                8e²
