$= \frac{\sqrt{10}}{5}$ $=color(blue)(sqrt10)/5$

$\frac{2}{\sqrt{10}}$ $2/(sqrt10)$

$= \frac{2 \cdot \sqrt{10}}{(\sqrt{10}) \cdot \sqrt{10}}$ $=(2 * color(blue)(sqrt10))/((sqrt10) *color(blue)(sqrt10)$

$= \frac{2 \sqrt{10}}{10}$ $=(2sqrt10)/(10)$

$= \frac{\sqrt{10}}{5}$ $=color(blue)(sqrt10)/5$
