| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{75}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{10} } \cdot \sqrt{75} = 5 \sqrt{30} $$ Simplify denominator. $$ \color{blue}{ \sqrt{75} } \cdot \sqrt{75} = 75 $$ |
| ③ | Divide both numerator and denominator by 5. |
