Solve the equation, give the exact solution then approximate the solution to the nearest hundredth if necessary

We solve as follows:
[tex]\frac{x^2}{3}=49\Rightarrow x^2=147[/tex][tex]\Rightarrow\begin{cases}x=7\sqrt[]{3} \\ x=-7\sqrt[]{3}\end{cases}[/tex]We have that the solutions for the problem are x = 7sqrt(3) or x = -7sqrt(3).
