Answer 1

Answer:

$( \frac{ - 5}{6} \times \frac{ - 5}{6} \times \frac{ - 5}{6} ) - ( \frac{ - 3}{2} \times \frac{ - 3}{2} \times \frac{ - 3}{2}) \times 3 \times 3 \\ = \frac{ - 125}{ 216} - ( \frac{ - 27}{8} )9 \\ = ( \frac{604}{216} ) \times 9 \\ = \frac{604}{72} \times 3 \\ = \frac{604}{24} \\ = = \frac{151}{6}$
