Question

In the equation 4x^3=56, what is the value of x

Answer 1

The given equation is

`4x^3=56_{}`

First, we divide the equation by 4.

`\begin{gathered} (4x^3)/(4)=(56)/(4) \\ x^3=14 \end{gathered}`

At last, we take the cubic root on each side.

`\begin{gathered} \sqrt[3]{x^3}=\sqrt[3]{14} \\ x\approx2.41 \end{gathered}`

Therefore, the value of x is 2.41, approximately.
