| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{74}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{26} } \cdot \sqrt{74} = 2 \sqrt{481} $$ Simplify denominator. $$ \color{blue}{ \sqrt{74} } \cdot \sqrt{74} = 74 $$ |
| ③ | Divide both numerator and denominator by 2. |
