Answer 2

Given:

The decimal have the cube as $\frac{1}{8}$.

To find:

The decimal have the cube as $\frac{1}{8}$ from the given decimals.

Solution:

We can find the decimal value have the cube as $\frac{1}{8}$ of finding the cube root value of $\frac{1}{8}$

$\sqrt[3]{\frac{1}{8} }$ = $\frac{\sqrt[3]{1}}{\sqrt[3]{8}}$

$\sqrt[3]{\frac{1}{8} }$ = $\frac{\sqrt[3]{(1)^{3} } }{\sqrt[3]{(2)^{3} } }$

$\sqrt[3]{\frac{1}{8} }$ = $\frac{1}{2}$

$\sqrt[3]{\frac{1}{8} }$ = 0.5

The decimal have the cube as $\frac{1}{8}$ is 0.5

Final answer:

The decimal have the cube as $\frac{1}{8}$ from the given decimals is 0.5

Thus, the correct option is b)0.5
