    Root simplification

    I have a really simple and idiotic question. I have no clue as to how to simplify root expressions. For example (sqrt(x)=the square root of x):

    sqrt(n)+1/sqrt(n+1)

    how can I deal with this expression and represent it as a multiple of n for example?

    thanks

    That cannot really be done. BUT
    \frac{\sqrt{n}+1}{\sqrt{n+1}}=\frac{(\sqrt{n}+1)( \sqrt{n+1})}{{n+1}}
    Not really what you seem to want.?
