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