The question is asking to rationalize the denominator of the expression $\frac{2}{\sqrt{5}}$.

To rationalize the denominator, we need to eliminate the square root in the denominator. This can be done by multiplying both the numerator and denominator by $\sqrt{5}$:

$\frac{2}{\sqrt{5}} \times \frac{\sqrt{5}}{\sqrt{5}} = \frac{2\sqrt{5}}{5}$

So, the rationalized form of $\frac{2}{\sqrt{5}}$ is $\frac{2\sqrt{5}}{5}$.

Tip: When rationalizing denominators, always multiply by the conjugate or the square root term needed to clear the irrationality in the denominator.
