Answer 1

$((3 {}^{3} ) \frac{2}{3} - 3 { }^{ - 2} ) \times (( {2}^{4} ) \frac{3}{4} - 16 - \frac{3}{4 } \\ (3 {}^{2} - \frac{1}{3 {}^{2} } ) \times ({2}^{3} - 2 {}^{ - 3} ) \\ (9 - \frac{1}{9} ) \times (8 \times \frac{1}{ {2}^{3} } ) \\ \frac{80}{9} \times ( - 8 \times \frac{1}{8} ) \\ \frac{80}{9} \times \frac{63}{8} \\ 10 \times 7 \\ = 70$
