To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately. For example, \(\sqrt{9 \over 16}\) = \({\sqrt{9}} \over {\sqrt{16}}\) = \({3 \over 4}\)
What is \( \sqrt{\frac{36}{81}} \)?
| 4\(\frac{1}{2}\) | |
| 1\(\frac{1}{5}\) | |
| \(\frac{2}{3}\) | |
| \(\frac{1}{3}\) |
