| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ 2 + \sqrt{3}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \left( 3 + \sqrt{2}\right) } \cdot \left( 2 + \sqrt{3}\right) = \color{blue}{3} \cdot2+\color{blue}{3} \cdot \sqrt{3}+\color{blue}{ \sqrt{2}} \cdot2+\color{blue}{ \sqrt{2}} \cdot \sqrt{3} = \\ = 6 + 3 \sqrt{3} + 2 \sqrt{2} + \sqrt{6} $$ Simplify denominator. $$ \color{blue}{ \left( 2- \sqrt{3}\right) } \cdot \left( 2 + \sqrt{3}\right) = \color{blue}{2} \cdot2+\color{blue}{2} \cdot \sqrt{3}\color{blue}{- \sqrt{3}} \cdot2\color{blue}{- \sqrt{3}} \cdot \sqrt{3} = \\ = 4 + 2 \sqrt{3}- 2 \sqrt{3}-3 $$ |
| ③ | Simplify numerator and denominator |
| ④ | Remove 1 from denominator. |
