I've tried multiplicating by the conjugate of the denominator and of the numerator but this leads to nothing I can see. How can this limit be evaluated? (the limit is to be taken when n goes to infinity)(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{\sqrt{n+7}-\sqrt{n+5}}{\sqrt{n+2}-\sqrt{n}}[/tex]

The answer is 1.

Thanks for helping.
