`(\sqrt{27}-3\sqrt{2}+2\sqrt{6}):3\sqrt{3}`
`=(3\sqrt{3}-3\sqrt{2}+2\sqrt{6}):3\sqrt{3}`
`=\sqrt{3}(3-\sqrt{6}+2\sqrt{2}):3\sqrt{3}`
`=(3-\sqrt{6}+2\sqrt{2}):3`
`=1-[\sqrt{6}-2\sqrt{2}]/3`

b)\(\dfrac{3}{2+\sqrt{3}}\)+\(\dfrac{13}{4-\sqrt{3}}\)+\(\dfrac{6}{\sqrt{3}}\)
Câu 1: Thực hiện phép tính:
a. \(\sqrt{3}\left(2\sqrt{6}-\sqrt{3}\right)-6\sqrt{2}\)
b. \(6\sqrt{12}-\sqrt{20}-2\sqrt{27}+\sqrt{125}\)
c. \(\sqrt{\left(1-\sqrt{3}\right)^2}-3\sqrt{\dfrac{1}{3}}\)
d. \(\dfrac{6}{\sqrt{6}}-\dfrac{5}{\sqrt{6}-1}\)
\(c,2\sqrt{\dfrac{16}{3}}-3\sqrt{\dfrac{1}{27}}-6\sqrt{\dfrac{4}{75}}\)
d,\(\sqrt{\dfrac{2-\sqrt{3}}{2+\sqrt{3}}}+\sqrt{\dfrac{2+\sqrt{3}}{2-\sqrt{3}}}\)
Bài 1. Tính
\(G=\sqrt[3]{2+10\sqrt{\frac{1}{27}}}+\sqrt[3]{2-10\sqrt{\frac{1}{27}}}\)
\(H=\sqrt[3]{1+\sqrt{2}}.\sqrt[6]{3-2\sqrt{2}}\)
\(\dfrac{\sqrt{6}+\sqrt{14}}{2\sqrt{3}+\sqrt{28}}\)
\(\dfrac{\sqrt{2}+\sqrt{3}+\sqrt{6}+\sqrt{8}+4}{\sqrt{2}+\sqrt{3}+\sqrt{4}}\)
