Tính:
\(a)E=\sqrt{\left|12\sqrt{5}-29\right|}-\sqrt{12\sqrt{5}+29}\\ b)\sqrt{\left|40\sqrt{2}-57\right|}-\sqrt{40\sqrt{2}+57}\)
A=\(\sqrt{24+16\sqrt{2}}-\sqrt{24-16\sqrt{2}}\)
B=\(\sqrt{57-40\sqrt{2}}-\sqrt{40\sqrt{2+57}}\)
C=\(\sqrt{\sqrt{5}-\sqrt{3}-\sqrt{29}-12\sqrt{5}}\)
Mọi người làm nhanh hộ mình nhé
Rút gọn :
\(a.\sqrt{17-12\sqrt{2}}+\sqrt{2}\)
\(b.\sqrt{4-2\sqrt{3}}+\sqrt{7-4\sqrt{3}}\)
\(c.\sqrt{\left|40\sqrt{2}-57\right|}-\sqrt{40\sqrt{2}+57}\)
1, \(\sqrt{21+12\sqrt{3}}\)
2, \(\sqrt{57-40\sqrt{2}}\)
3, \(\sqrt{\left(\sqrt{5}+1\right)^2}+\sqrt{\left(\sqrt{5-1}^2\right)}\)
Tính
a.\(\sqrt{19-6\sqrt{2}}\) b.\(\sqrt{11-6\sqrt{2}}\) c.\(\sqrt{9-6\sqrt{2}}\)
d.\(\sqrt{21+12\sqrt{3}}\) e.\(\sqrt{57-40\sqrt{2}}\)
a) A=\(\sqrt{\left(4-\sqrt{15}\right)^2+\sqrt{15}}\)
b) B=\(\sqrt{\left(2-\sqrt{3}\right)^2}+\sqrt{\left(1-\sqrt{3}\right)^2}\)
c) C=\(\sqrt{49-12\sqrt{5}}-\sqrt{49+12\sqrt{5}}\)
d)D=\(\sqrt{29+12\sqrt{5}-\sqrt{29-12\sqrt{5}}}\)
1)Tính:
a) \(\sqrt{\sqrt{5}-\sqrt{3-\sqrt{29-12\sqrt{5}}}}\)
b) \(\sqrt{6+2\sqrt{5}-\sqrt{29-12\sqrt{5}}}\)
c)\(\sqrt{2 +\sqrt{5-\sqrt{13+\sqrt{48}}}}\)
\(\sqrt{5}-\sqrt{3-\sqrt{29-12\sqrt{5}}}=\sqrt{5}-\sqrt{3\sqrt{\left(\sqrt{20-3}\right)^2}}\)
\(\sqrt{\sqrt{5}-\sqrt{3-\sqrt{29-6\sqrt{20}}}}\)
\(\sqrt{6+2\sqrt{5-\sqrt{13+\sqrt{48}}}}\)
Bài 1 : tính
a)\(\sqrt{49-12\sqrt{5}}+\sqrt{49+12\sqrt{5}}\)
b)\(\sqrt{29+12\sqrt{5}}+\sqrt{29-12\sqrt{5}}\)
