① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{25}} $$. |
② | Multiply in a numerator. $$ \color{blue}{ \sqrt{6} } \cdot \sqrt{25} = 5 \sqrt{6} $$ Simplify denominator. $$ \color{blue}{ 3 \sqrt{25} } \cdot \sqrt{25} = 75 $$ |
③ | Divide both numerator and denominator by 5. |
