第481题:二次根式的加减运算
计算.
(24−0.5+223)\left( \sqrt{24} -\sqrt{0.5} +2\sqrt{\dfrac{2}{3}} \right)(√24−√0.5+2√32)−(18−6)- \left( \sqrt{\dfrac{1}{8}} - \sqrt{6} \right)−(√81−√6) === ( ).
A. 1336−342\dfrac{13}{3} \sqrt{6}-\dfrac{3}{4}\sqrt{2}313√6−43√2
B. 1136−432\dfrac{11}{3} \sqrt{6}-\dfrac{4}{3}\sqrt{2}311√6−34√2
C. 1336−432\dfrac{13}{3} \sqrt{6}-\dfrac{4}{3}\sqrt{2}313√6−34√2
D. 1136−342\dfrac{11}{3} \sqrt{6}-\dfrac{3}{4}\sqrt{2}311√6−43√2
提示:先将二次根式化成最简二次根式,再将被开方数相同的二次根式进行合并.
