| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{8}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 3 } \cdot \sqrt{8} = 6 \sqrt{2} $$ Simplify denominator. $$ \color{blue}{ 2 \sqrt{8} } \cdot \sqrt{8} = 16 $$ |
| ③ | Divide numerator and denominator by $ \color{blue}{ 2 } $. |
