| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{33}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 3 \sqrt{11} } \cdot \sqrt{33} = 33 \sqrt{3} $$ Simplify denominator. $$ \color{blue}{ \sqrt{33} } \cdot \sqrt{33} = 33 $$ |
| ③ | Divide both numerator and denominator by 33. |
