Las expresiones son:
![\sqrt{4}-\sqrt{36 \sqrt{4}-\sqrt{36](https://tex.z-dn.net/?f=%5Csqrt%7B4%7D-%5Csqrt%7B36)
![\textup{como}\,\sqrt{4}=2\,\textup{y}\,\sqrt{36}=6\,\textup{se sigue que}\\2-6=\\-4 \textup{como}\,\sqrt{4}=2\,\textup{y}\,\sqrt{36}=6\,\textup{se sigue que}\\2-6=\\-4](https://tex.z-dn.net/?f=%5Ctextup%7Bcomo%7D%5C%2C%5Csqrt%7B4%7D%3D2%5C%2C%5Ctextup%7By%7D%5C%2C%5Csqrt%7B36%7D%3D6%5C%2C%5Ctextup%7Bse+sigue+que%7D%5C%5C2-6%3D%5C%5C-4)
