Answer 1

$( \sqrt{6561} \times (3 \frac{37}{90} \times \frac{10}{279} ) - ( \frac{4}{3} ) {}^{ - 2} \times \frac{4}{9} ) \times ( - \frac{6}{ \sqrt{7} } ) \times \frac{1}{10} \\ \\ = (81 \times \frac{307}{2511} - ( \frac{3}{4} ) {}^{2} \times ( \frac{4}{9} )) \times ( \frac{6}{ \sqrt{7} } ) {}^{2} \times \frac{1}{10} \\ \\ = ( \frac{307}{31} - \frac{9}{16} \times \frac{4}{9} ) \times \frac{36}{7} \times \frac{1}{10} \\ \\ = ( \frac{307}{30} - \frac{1}{4} ) \times \frac{36}{7} \times \frac{1}{10} \\ \\ \frac{1228 - 31}{124} \times \frac{36}{7} \times \frac{1}{10} \\ \\ = \frac{1197}{124} \times \frac{36}{7} \times \frac{1}{10} \\ \\ = \frac{171}{31} \times 9 \times \frac{1}{10} \\ \\ = \frac{1539}{310}$
