= [\frac{- ln ( x ) - 9 x ^{9} \cdot \int - \frac{1}{9 x ^{10}} d x}{9 x ^{9}}]_{1}^{e}

\int - \frac{1}{9 x ^{10}} d x = \frac{1}{81 x ^{9}}

= [\frac{- ln ( x ) - 9 x ^{9} \frac{1}{81 x ^{9}}}{9 x ^{9}}]_{1}^{e}

\frac{- ln ( x ) - 9 x ^{9} \frac{1}{81 x ^{9}}}{9 x ^{9}} = \frac{- 9 ln ( x ) - 1}{81 x ^{9}}

= [\frac{- 9 ln ( x ) - 1}{81 x ^{9}}]_{1}^{e}
