2/√5

The expression \( \frac{2}{\sqrt{5}} \) can be rationalized by multiplying the numerator and the denominator by \( \sqrt{5} \): \[ \frac{2}{\sqrt{5}} \cdot \frac{\sqrt{5}}{\sqrt{5}} = \frac{2\sqrt{5}}{5} \] So, \( \frac{2}{\sqrt{5}} \) can be expressed as \( \frac{2\sqrt{5}}{5} \) when rationalized.
