When we find a root that is in the complete quotient (in the complete fraction), we can break down the factors of the quotient: the numerator and the denominator and leave the root separated for each of them. We will not forget to leave the division symbol: the dividing line between the factors we separate.

**Let's put it this way:**

$\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}$
