a) \(\sqrt{\left(\frac{1}{\sqrt{2}}-\frac{1}{2}\right)^2}\)
b) \(\sqrt{\left(2\sqrt{2-3}\right)^2}\)
c) \(\sqrt{\left(3-2\sqrt{2}\right)^2+\sqrt{\left(3+2\sqrt{2}\right)^2}}\)
d) \(\sqrt{\left(5-2\sqrt{6}\right)^2-\sqrt{\left(5+2\sqrt{6}\right)^2}}\)
e) \(\sqrt{\left(2-\sqrt{3}\right)^2+\sqrt{\left(1-\sqrt{3}\right)^2}}\)
f) \(\sqrt{\left(3+\sqrt{2}\right)^2-\sqrt{\left(1-\sqrt{2}\right)^2}}\)
a/ \(\sqrt{\left(\frac{1}{\sqrt{2}}-\frac{1}{2}\right)^2}=\) \(|\frac{1}{\sqrt{2}}-\frac{1}{2}|\)
\(=|\frac{\sqrt{2}-1}{2}|\)
\(=\frac{\sqrt{2}-1}{2}\)
các câu còn lại tương tự nha
chúc bn học tốt
