| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{175}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{35} } \cdot \sqrt{175} = 35 \sqrt{5} $$ Simplify denominator. $$ \color{blue}{ \sqrt{175} } \cdot \sqrt{175} = 175 $$ |
| ③ | Divide both numerator and denominator by 35. |
