Question

Using squares cube roots and reciprocals tables, solve: 2/∛21.36

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.

$\frac{2}{\sqrt[3]{21.36}}=\frac{2}{2.77460}$

Divide the numbers, we get

             $=0.72082$

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