Multiply the numerator and denominator times $\sqrt{5}$ $sqrt(5)$ .

$\frac{2}{\sqrt{5}} \cdot \frac{\sqrt{5}}{\sqrt{5}} = \frac{2 \sqrt{5}}{5}$ $(2)/(sqrt (5))*(sqrt (5))/(sqrt (5))=(2sqrt(5))/(5)$

Answer 2 · 2015-04-06T23:43:33

Try rationalizing by multiplying and dividing by $\sqrt{5}$ $sqrt(5)$ ., i.e.:
$\frac{2}{\sqrt{5}} \cdot \frac{\sqrt{5}}{\sqrt{5}} =$ $2/sqrt(5)*sqrt(5)/sqrt(5)=$ and see what happens!
