| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{36}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 4 \sqrt{4} } \cdot \sqrt{36} = 48 $$ Simplify denominator. $$ \color{blue}{ 2 \sqrt{36} } \cdot \sqrt{36} = 72 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 24 } $. |
