আবার, \(x=\cfrac{2\sqrt{15}}{\sqrt5+\sqrt3}\)
বা, \(\cfrac{x}{\sqrt5}=\cfrac{2\sqrt{15}}{\sqrt5(\sqrt5+\sqrt3)}\)
বা, \(\cfrac{x}{\sqrt5}=\cfrac{2\sqrt{3}}{(\sqrt5+\sqrt3)}\)
বা, \(\cfrac{x+\sqrt5}{x-\sqrt5}=\cfrac{2\sqrt{3}+(\sqrt5+\sqrt3)}{2\sqrt{3}-(\sqrt5+\sqrt3)}\)

বা, \(\cfrac{x+\sqrt5}{x-\sqrt5}=\cfrac{3\sqrt{3}+\sqrt5}{\sqrt{3}-\sqrt5}\)
\(\cfrac{x+\sqrt3}{x-\sqrt3}\) \(+\cfrac{x+\sqrt5}{x-\sqrt5}\)
\(=\cfrac{3\sqrt{5}+\sqrt3}{\sqrt{5}-\sqrt3}+\cfrac{3\sqrt{3}+\sqrt5}{\sqrt{3}-\sqrt5}\)
\(=\cfrac{3\sqrt{5}+\sqrt3}{\sqrt{5}-\sqrt3}-\cfrac{3\sqrt{3}+\sqrt5}{\sqrt5-\sqrt3}\)
\(=\cfrac{3\sqrt{5}+\sqrt3-3\sqrt{3}-\sqrt5}{\sqrt5-\sqrt3}\)
\(=\cfrac{2\sqrt{5}-2\sqrt{3}}{\sqrt5-\sqrt3}\)
\(=\cfrac{2(\sqrt{5}-\sqrt{3})}{(\sqrt5-\sqrt3)}\)
\(=2\)
