| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{25}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{4} } \cdot \sqrt{25} = 10 $$ Simplify denominator. $$ \color{blue}{ \sqrt{25} } \cdot \sqrt{25} = 25 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 5 } $. |
