Question

[Lương Ngọc Anh]

Tính 
G.\(\sqrt{7-2\sqrt{6}}\)
H.\(\sqrt{13-4\sqrt{3}}\)
I. \(\sqrt{7-4\sqrt{3}}\)\(-2\)
J.\(\sqrt{15-6\sqrt{6}}\)+\(\sqrt{33-12\sqrt{6}}\)

Answer 1

[Nguyễn Lê Phước Thịnh]

g: \(=\left|\sqrt{6}-1\right|=\sqrt{6}-1\)

h: \(=\left|2\sqrt{3}-1\right|=2\sqrt{3}-1\)

l: \(=\left|2-\sqrt{3}\right|-2=2-\sqrt{3}-2=-\sqrt{3}\)

j: \(=\left|3-\sqrt{6}\right|+\left|2\sqrt{6}-3\right|\)

\(=3-\sqrt{6}+2\sqrt{6}-3=\sqrt{6}\)
