\(=\left[\dfrac{2+\sqrt{3}}{2}:\left(1+\sqrt{\dfrac{4+2\sqrt{3}}{4}}\right)\right]+\left[\dfrac{2-\sqrt{3}}{2}:\left(1-\sqrt{\dfrac{4-2\sqrt{3}}{4}}\right)\right]\)
\(=\left(\dfrac{2+\sqrt{3}}{2}:\dfrac{2+\sqrt{3}+1}{2}\right)+\left(\dfrac{2-\sqrt{3}}{2}:\dfrac{2-\sqrt{3}+1}{2}\right)\)
\(=\dfrac{2+\sqrt{3}}{3+\sqrt{3}}+\dfrac{2-\sqrt{3}}{3-\sqrt{3}}\)
\(=1\)
