Answer: d. 512

Explanation:

You need to remember that:

$(\sqrt[3]{x})^3=x$

Then, given the equation:

$\sqrt[3]{n}=8$

You can find the value of "n" that make the equation true, by solving for "n".

So, to solve for "n", you need to raise both side of the equation to power 3. Therefore, you get:

$\sqrt[3]{n}=8$

$(\sqrt[3]{n})^3=(8)^3$

n=512

Then, the value of "n" that makes the equation
$\sqrt[3]{n}=8$ true is: 512 (You can observe that this matches with the option d).
