Answer 1

Given:

`$\frac{2}{\sqrt[3]{21.36}}`

To find:

The value of the expression.

Solution:

`$\frac{2}{\sqrt[3]{21.36}}`

Let us first solve denominator:

`\sqrt[3]{21.36}=2.77460`

Substitute this into the given expression.

`$\frac{2}{\sqrt[3]{21.36}}=(2)/(2.77460)`

Divide the numbers, we get

`=0.72082`

Therefore,
`\frac{2}{\sqrt[3]{21.36}} =0.72082`.
