\(\sqrt{\left(3-\sqrt{10}\right)^2}+\sqrt{11-2\sqrt{10}}\)
tính
\(\sqrt{28-10\sqrt{3}}\)
\(\sqrt{41+12\sqrt{5}}\)
\(\sqrt{32-10\sqrt{7}}\)
\(\sqrt{11-4\sqrt{7}}\)
Rút gọn:
\(A=\sqrt{11-2\sqrt{10}}+\sqrt{9-2\sqrt{4}}-\sqrt{10}-\sqrt{7}\)
\(B=\frac{\sqrt{3}+\sqrt{11+2\sqrt{6}}-\sqrt{5+2\sqrt{6}}}{\sqrt{2}+\sqrt{6+2\sqrt{5}}-\sqrt{7+2\sqrt{10}}}\)
Tính
\(\frac{\sqrt{45+27\sqrt{2}}+\sqrt{45-27\sqrt{2}}}{\sqrt{5+3\sqrt{2}}-\sqrt{5-3\sqrt{2}}}-\frac{\sqrt{3+\sqrt{2}}+\sqrt{3-\sqrt{2}}}{\sqrt{3+\sqrt{2}}-\sqrt{3-\sqrt{2}}}\)
\(\sqrt{\sqrt{11}+1}.\sqrt{\sqrt{11}-1}+\sqrt{10}\)
\(\sqrt{11+2\sqrt{18}}\)
\(\sqrt{7+2\sqrt{10}}\)
\(\sqrt{7+4\sqrt{3}}\)
\(\sqrt{12-2\sqrt{55}}\)
So sánh
a) 2 và 1+\(\sqrt{2}\)
b) 4 và 1+\(\sqrt{3}\)
c) -2\(\sqrt{11}\) và -10
d) 3\(\sqrt{11}\) và 12
\(\left(\sqrt{11}-\sqrt{3}\right)\left(\sqrt{13-\sqrt{6}+2\sqrt{30-\sqrt{54}}}+\sqrt{11}-\sqrt{10-\sqrt{6}}\right)\)
