<s>[INST] Simplifying some square numbers expressions I need help to fix theese out. Thank you.
$ \frac { \frac {1} {\sqrt {3} } - \sqrt {12} } { \sqrt {3} } $

$ \frac { \sqrt {x} } {\sqrt[3] {3} } + \frac {\sqrt[4] {x}} {\sqrt {x} } $

$ \sqrt {5} - \sqrt {3} = n \Rightarrow \sqrt {5} + \sqrt {3} = ? $ 
 [/INST] If $$\left(\sqrt{5}-\sqrt{3}\right) = n\;,$$ Then $$\left(\sqrt{5}-\sqrt{3}\right)\cdot \left(\sqrt{5}+\sqrt{3}\right)= n\cdot \left(\sqrt{5}+\sqrt{3}\right)$$
So we get $$\displaystyle \left(\sqrt{5}+\sqrt{3}\right) = \frac{2}{n}$$
