$\frac{\sqrt{81}}{\sqrt{20}} = \frac{\sqrt{9 \cdot 9}}{\sqrt{2 \cdot 2 \cdot 5}} = \frac{9}{2 \sqrt{5}} = \frac{9 \cdot \sqrt{5}}{2 \cdot \sqrt{5} \cdot \sqrt{5}} = \frac{9 \sqrt{5}}{2 \cdot 5} = \frac{9 \sqrt{5}}{10}$ $sqrt81 / sqrt20 = sqrt(9*9) /sqrt(2*2*5) = 9/(2sqrt5) = (9*sqrt5)/(2*sqrt5*sqrt5) = (9sqrt5)/(2*5) = (9 sqrt5) /10$
