| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{50}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{10} } \cdot \sqrt{50} = 10 \sqrt{5} $$ Simplify denominator. $$ \color{blue}{ \sqrt{50} } \cdot \sqrt{50} = 50 $$ |
| ③ | Divide both numerator and denominator by 10. |
