Question

Can anyone help me with this question

Answer 1

`- 3`

EXPLANATION

The given expression is

`(2)/(3) √(81) - \sqrt[3]{ - 27} - (4)/(3) \sqrt[3]{729}`

We simplify the expressions under the radical sign to obtain:

`(2)/(3) \sqrt{ {9}^(2) } - \sqrt[3]{ - {3}^(3) } - (4)/(3) \sqrt[3]{ {9}^(3) }`

We simplify to obtain;

`(2)/(3) * 9 - ( - 3) - (4)/(3) * 9`

This will be equal to:

`6 + 3- 12 = - 3`

The last option is correct.
