a) \(\sqrt{4-2\sqrt{3}}=\sqrt{3}-1\)
b) \(\sqrt{9-4\sqrt{5}}=\sqrt{10}-1\)
c) \(\sqrt{12+6\sqrt{3}}=3+\sqrt{3}\)
d) \(\sqrt{30-12\sqrt{6}}=3\sqrt{2}-2\sqrt{3}\)
e) \(\sqrt{8-\sqrt{60}}=\sqrt{5}-\sqrt{3}\)
f) \(\sqrt{-\sqrt{96}+25}=2\sqrt{6}-1\)
g: Ta có: \(\sqrt{7+4\sqrt{3}}-\sqrt{4+2\sqrt{3}}\)
\(=2+\sqrt{3}-\sqrt{3}-1\)
=1
h: Ta có: \(\sqrt{3-2\sqrt{2}}+\sqrt{6-4\sqrt{2}}\)
\(=\sqrt{2}-1+2-\sqrt{2}\)
=1
