To simplify the expression \(\frac{\sqrt{10}}{\sqrt{2}}\), you can use the property of square roots that states \(\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}\).
So, we have:
\[ \frac{\sqrt{10}}{\sqrt{2}} = \sqrt{\frac{10}{2}} = \sqrt{5} \]
Therefore, the exact answer is \(\sqrt{5}\).
So to clarify your options, it's neither four square roots of five, nor two square roots of 10, nor two square roots of five; it simplifies directly to just \(\sqrt{5}\).
