$8. \: 2a {}^{3} = - \frac{3}{7} \: | \div 2 \\ a {}^{3} = - \frac{3}{14}$

$40 \times ( - \frac{3}{14}) {}^{3} = - \frac{135}{ 343}$

$9. \: \frac{48 {}^{5} }{27 {}^{2} \times 4 {}^{9} } = \frac{(3 \times 4 {}^{2}) {}^{5} }{3 {}^{5} \times 4 {}^{9} } = \frac{4 {}^{10} }{4 {}^{9} } = 4$

10. (8х⁶у³)² = 64х¹²у⁶

(-8х⁶y³)² = 64х¹²у⁶
