To multiply or divide radicals, multiply or divide the coefficients and radicands separately: \(x\sqrt{a} \times y\sqrt{b} = xy\sqrt{ab}\) and \({x\sqrt{a} \over y\sqrt{b}} = {x \over y}\sqrt{a \over b}\)
What is \( \frac{10\sqrt{16}}{2\sqrt{4}} \)?
| \(\frac{1}{4}\) \( \sqrt{\frac{1}{5}} \) | |
| \(\frac{1}{4}\) \( \sqrt{5} \) | |
| 5 \( \sqrt{4} \) | |
| 5 \( \sqrt{\frac{1}{4}} \) |
