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.

$\begin{gathered} \frac{4x^3}{4}=\frac{56}{4} \\ x^3=14 \end{gathered}$

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.
