Answer
$\dfrac{2\sqrt 3}{3}$
Work Step by Step
Rationalize the denominator by multiplying $\sqrt3$ to both the numerator and the denominator:
$\dfrac{2}{\sqrt 3}
=\dfrac{2}{\sqrt 3} \cdot \dfrac{\sqrt 3}{\sqrt 3}$
Simplify.
$=\dfrac{2\sqrt 3}{(\sqrt 3)^2}$
$=\dfrac{2\sqrt 3}{3}$
Hence, the correct answer is $\frac{2\sqrt 3}{3}$.
