Ta có: \(\sqrt{\dfrac{2}{3-\sqrt{5}}}+\sqrt{\dfrac{2}{7+3\sqrt{5}}}\)
\(=\sqrt{\dfrac{4}{6-2\sqrt{5}}}+\sqrt{\dfrac{4}{14+6\sqrt{5}}}\)
\(=\dfrac{2}{\sqrt{5}-1}+\dfrac{2}{3+\sqrt{5}}\)
\(=\dfrac{2\left(\sqrt{5}+1\right)}{4}+\dfrac{2\left(3-\sqrt{5}\right)}{4}\)
\(=\dfrac{\sqrt{5}+1+3-\sqrt{5}}{2}\)
