Square root of a quotient

🏆Practice square root quotient property

Root of a quotient

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:

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

Choose the expression that is equal to the following:

\( \sqrt{a}:\sqrt{b} \)

Practice more now

Let's look at this in the example

10064\sqrt{\frac{100}{64}}
According to the quotient root rule, we can break down the factors and leave the root of each factor separately while maintaining the multiplication operation between them:
We will break it down and obtain:
10064\frac{\sqrt{100}}{\sqrt{64}}

10×8=8010\times 8=80
