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