Question

[(⅔)²]³×[⅔]-8×3²×1/9​

Answer 1

${(( { \frac{2}{3}) }^{2} )}^{3} \times (\frac{2}{3}) - 8 \times {3}^{2} \times \frac{1}{9}$

$= {( \frac{4}{9} )}^{3} \times \frac{2}{3} - 8 \times 9 \times \frac{1}{9}$

$= \frac{64}{729} \times \frac{2}{3} - 8$

$= 0.0877914952 \times 0.6666666667 - 8$

$= 0.0585276635 - 8$

$= - 7.94147233653$
