Ta có \(\sqrt{8-\sqrt{60}}+\sqrt{4-\sqrt{12}}\)
\(=\sqrt{8-2\sqrt{15}}+\sqrt{4-\sqrt{12}}=\sqrt{5-2\sqrt{3}.\sqrt{5}+3}+\sqrt{3-2\sqrt{3}+1}\)
\(=\sqrt{\left(\sqrt{5}-\sqrt{3}\right)^2}+\sqrt{\left(\sqrt{3}-1\right)^2}=\left|\sqrt{5}-\sqrt{3}\right|+\left|\sqrt{3}-1\right|=\sqrt{5}-\sqrt{3}+\sqrt{3}-1\)
\(=\sqrt{5}-1\)
Chúc bạn học tốt =))
