① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{4}} $$. |
② | Multiply in a numerator. $$ \color{blue}{ \sqrt{3} } \cdot \sqrt{4} = 2 \sqrt{3} $$ Simplify denominator. $$ \color{blue}{ \sqrt{4} } \cdot \sqrt{4} = 4 $$ |
③ | Divide both numerator and denominator by 2. |
