Question

An equation is shown below with a missing value.

Answer 1

Answer:

The missing value is 512

$8=\sqrt[3]{512}$

Step-by-step explanation:

Let

x ----> the missing value

we have

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

solve for x

That means-----> isolate the variable x

Elevated both sides to the cube

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

Remember that

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

so

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

substitute

$8^{3}=x$

$512=x$

Rewrite

$x=512$

so

the equation is

$8=\sqrt[3]{512}$
