| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{2}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 6 \sqrt{5} } \cdot \sqrt{2} = 6 \sqrt{10} $$ Simplify denominator. $$ \color{blue}{ 3 \sqrt{2} } \cdot \sqrt{2} = 6 $$ |
| ③ | Divide both numerator and denominator by 6. |
