\[\large \frac{10}{\sqrt{5}}\neq \frac{2}{\sqrt{5}}\]

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

oh ok, yeah rationalize the denominator by multiplying both top and bottom by sqrt(5) to get your answer

OpenStudy (zarkon):

\[\frac{10}{\sqrt{5}}=\frac{10}{\sqrt{5}}\frac{\sqrt{5}}{\sqrt{5}}=\frac{10\sqrt{5}}{5}=2\sqrt{5}\]
