| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{13}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 6 } \cdot \sqrt{13} = 6 \sqrt{13} $$ Simplify denominator. $$ \color{blue}{ 3 \sqrt{13} } \cdot \sqrt{13} = 39 $$ |
| ③ | Divide numerator and denominator by $ \color{blue}{ 3 } $. |
