    sqrt fractions

    How do I do \frac{\sqrt{n+3}}{\sqrt{n}} please?

    Can it be simplified more?

    You can re-arrange the fraction so that the denominator is not a root:

    \frac{\sqrt{n+3}\cdot \sqrt{n}}{\sqrt{n}\cdot \sqrt{n}} = \dfrac1n \sqrt{n^2+3n}

    But I don't know if this is simpler ...
