① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{50}} $$. |
② | Multiply in a numerator. $$ \color{blue}{ \sqrt{35} } \cdot \sqrt{50} = 5 \sqrt{70} $$ Simplify denominator. $$ \color{blue}{ \sqrt{50} } \cdot \sqrt{50} = 50 $$ |
③ | Divide both numerator and denominator by 5. |
