| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{16}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{4} } \cdot \sqrt{16} = 8 $$ Simplify denominator. $$ \color{blue}{ 3 \sqrt{16} } \cdot \sqrt{16} = 48 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 8 } $. |
