计算:
\((1)( \sqrt{24}- \sqrt{2})-( \sqrt{8}+ \sqrt{6}) \); \((2) \sqrt{6}× \sqrt{15}× \sqrt{10} \)
\((3)\) \( \sqrt{(2+ \sqrt{3}{)}^{2005}}× \sqrt{(2- \sqrt{3}{)}^{2005}} \) \((4) \sqrt{1 \dfrac{2}{3}}÷( \sqrt{2 \dfrac{1}{3}}÷ \sqrt{1 \dfrac{2}{5}}) \)
\(⑸ \sqrt{12}÷( \dfrac{1}{ \sqrt{3}}- \dfrac{1}{ \sqrt{12}}) \) \(⑹ \dfrac{1}{1+ \sqrt{2}}+ \dfrac{1}{ \sqrt{2}+ \sqrt{3}}+ \dfrac{1}{ \sqrt{3}+ \sqrt{4}}+…+ \dfrac{1}{ \sqrt{99}+ \sqrt{100}} \)
