| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{23}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 2 \sqrt{23} } \cdot \sqrt{23} = 46 $$ Simplify denominator. $$ \color{blue}{ \sqrt{23} } \cdot \sqrt{23} = 23 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 23 } $. |
| ④ | Remove 1 from denominator. |
