Question

What is the answer of (-2/3)^3+(-3/2)^3?​

Answer 1

Answer:

${ (\frac{ - 2}{3}) }^{3} + ( { \frac{ - 3}{2} )}^{3} \\ = \frac{ - 8}{27} + \frac{ - 27}{8} \\ = \frac{ - 64 + ( - 729)}{216} \\ = \frac{ - 64 - 729}{216} \\ = \frac{ - 793}{216} \\ \boxed{= \underline{ \underline{- 3 \frac{145}{216} }}}$
