Step-by-step explanation:
The square root is
![\sqrt{\frac{144}{256}} = \frac{3}{4}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B144%7D%7B256%7D%7D%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
Just square the top and bottom of the fraction.
![\sqrt{144} = 12](https://tex.z-dn.net/?f=%5Csqrt%7B144%7D%20%3D%2012)
and
![\sqrt{256} = 16](https://tex.z-dn.net/?f=%5Csqrt%7B256%7D%20%3D%2016)
so we have 12/16 and then we reduce to 3/4
