| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{31}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{93} } \cdot \sqrt{31} = 31 \sqrt{3} $$ Simplify denominator. $$ \color{blue}{ 2 \sqrt{31} } \cdot \sqrt{31} = 62 $$ |
| ③ | Divide both numerator and denominator by 31. |
