Question

Can anyone help me with this question

Answer 1

ANSWER

$- 3$

EXPLANATION

The given expression is

$\frac{2}{3} \sqrt{81} - \sqrt[3]{ - 27} - \frac{4}{3} \sqrt[3]{729}$

We simplify the expressions under the radical sign to obtain:

$\frac{2}{3} \sqrt{ {9}^{2} } - \sqrt[3]{ - {3}^{3} } - \frac{4}{3} \sqrt[3]{ {9}^{3} }$

We simplify to obtain;

$\frac{2}{3} \times 9 - ( - 3) - \frac{4}{3} \times 9$

This will be equal to:

$6 + 3- 12 = - 3$

The last option is correct.
