| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{3}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \left( 2 \sqrt{3}- \sqrt{6}\right) } \cdot \sqrt{3} = \color{blue}{ 2 \sqrt{3}} \cdot \sqrt{3}\color{blue}{- \sqrt{6}} \cdot \sqrt{3} = \\ = 6- 3 \sqrt{2} $$ Simplify denominator. $$ \color{blue}{ \sqrt{3} } \cdot \sqrt{3} = 3 $$ |
| ③ | Divide both numerator and denominator by 3. |
| ④ | Remove 1 from denominator. |
