Limit as x approaches 0 √5+x - √5/x I started working on this problem but... √5+x - √5/x (√5+x - √5/x)(√5+x + √5/√5+x + √5) ... I have no idea what to do because there are two radicals in the numerator.

Is this your problem? $\displaystyle \displaystyle \lim_{x \to 0} \sqrt{5}+x-\frac{\sqrt{5}}{x}$ or is it this? $\displaystyle \displaystyle \lim_{x \to 0} \frac{\sqrt{5}+x-\sqrt{5}}{x}$
It looks like this $\displaystyle \displaystyle \lim_{x \to 0} \frac{\sqrt{5}+x-\sqrt{5}}{x}$ except 5 + x is under one radical sign.
