Answer:
![\frac{7\sqrt{6}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Csqrt%7B6%7D%7D%7B2%7D)
Step-by-step explanation:
To rationalize the denominator, all you have to do is multiply the top and bottom by √6:
![\frac{21}{\sqrt{6}}\cdot\frac{\sqrt{6}}{\sqrt{6}} = \frac{21\sqrt{6}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B%5Csqrt%7B6%7D%7D%5Ccdot%5Cfrac%7B%5Csqrt%7B6%7D%7D%7B%5Csqrt%7B6%7D%7D%20%3D%20%5Cfrac%7B21%5Csqrt%7B6%7D%7D%7B6%7D)
You can further simplify by dividing the top and bottom by 3:
![\frac{7\sqrt{6}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Csqrt%7B6%7D%7D%7B2%7D)
I hope this helped.
