Question

como calcular essa expressão?? me ajudem ​

Answer 1

$\sqrt[3]{-729}= 9i$

$64^{1/3}= \sqrt[3]{64}= 4$

$\sqrt[3]{-27}= 3i$

$4^{1/2} = \sqrt{4} = 2$

$81^{1/4} = \sqrt[4]{81} = 3$

$3^{-2} = 1/9\\\\2^{-3} = 1/8\\\\3^0 = 1$

$((1/9) / (1/8)) = 8/9$

$\frac{4/3i}{2/3}= \frac{12i}{6} = 2i$

$9i * (2i - 8/9)\\18i^2 - 72i/9\\18i^2 - 8i$
