Explicação passo-a-passo:

$\mathsf{x = \dfrac{2}{3} \times \dfrac{2}{8^3} - \dfrac{2}{3} - \dfrac{2}{8^3}}$

$\mathsf{x = \dfrac{2}{3} \times \dfrac{2}{512} - \dfrac{2}{3} - \dfrac{2}{512}}$

$\mathsf{x = \dfrac{4}{1.536} - \dfrac{2}{3} - \dfrac{2}{512}}$

$\mathsf{x = \dfrac{4 - 1.024 - 6}{1.536}}$

$\mathsf{x = -\dfrac{1.026}{1.536}}$

$\boxed{\boxed{\mathsf{x = -\dfrac{171}{256}}}}$
