Question

ans this maths question please solve in notebook​

Answer 1

${ (- 2 - \frac{1}{3}i) }^{3} \\ \\ = { (\frac{ - 6 - i}{3}) }^{3} \\ \\ = \frac{ {( - 6 - i)}^{3} }{ {3}^{3} } \\ \\ = \frac{ - 216 - {i}^{3} - 3( -6)i( - 6 - i) }{27} \\ \\ = \frac{ - 216 + i - 108i + 18}{27} \\ \\ = \frac{198 - 107i}{27} \\ \\ = \frac{198}{27} - \frac{107i}{27}$

Thus expressed
