ANSWER:

General solution:


x=(\pi)/(6)+n\pi

Solution over the given interval:


x=(\pi)/(6)

Step-by-step explanation:

Let's solve for tan(x),


\begin{gathered} 2\sqrt[]{3}\tan (x)-2=0\rightarrow2\sqrt[]{3}\tan (x)=2 \\ \rightarrow\sqrt[]{3}\tan (x)=1\rightarrow\tan (x)=\frac{1}{\sqrt[]{3}} \\ \\ \Rightarrow\tan (x)=\frac{\sqrt[]{3}}{3} \end{gathered}

Now, we'll use the inverse trigonometric function for tangent:


\begin{gathered} \tan (x)=\frac{\sqrt[]{3}}{3}\rightarrow x=\tan ^(-1)(\frac{\sqrt[]{3}}{3}) \\ \\ \Rightarrow x=(\pi)/(6) \end{gathered}

Now, since tan(x) has a period of pi, the general solution for the equation is:


x=(\pi)/(6)+n\pi,n\in Z

For the interval [0,pi] we'll have the solution:


x_{}=(\pi)/(6)
