[tex]= \frac{9 \sqrt{11} - \sqrt{33} - 81 + 9 \sqrt{3}}{81 - 9 \sqrt{3} + 9 \sqrt{3} - \sqrt{9}} [/tex]
[tex]= \frac{9 \sqrt{11} - \sqrt{33} - 81 + 9 \sqrt{3}}{81 - \sqrt{9}}[/tex]
[tex]= \frac{9 \sqrt{11} - \sqrt{33} - 81 + 9 \sqrt{3}}{81 - 3} = \frac{9 \sqrt{11} - \sqrt{33} - 81 + 9 \sqrt{3}}{78} [/tex]
