① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{33}} $$. |
② | Multiply in a numerator. $$ \color{blue}{ \sqrt{60} } \cdot \sqrt{33} = 6 \sqrt{55} $$ Simplify denominator. $$ \color{blue}{ \sqrt{33} } \cdot \sqrt{33} = 33 $$ |
③ | Divide numerator and denominator by $ \color{blue}{ 3 } $. |
