Bài 1 : tính
a)\(\sqrt{49-12\sqrt{5}}+\sqrt{49+12\sqrt{5}}\)
b)\(\sqrt{29+12\sqrt{5}}+\sqrt{29-12\sqrt{5}}\)
a)\(\sqrt{29-12\sqrt{5}}\)
b) \(\sqrt{\sqrt{5}-\sqrt{3-\sqrt{29-12\sqrt{5}}}}\)
tính \(\sqrt{57-40\sqrt{2}}-\sqrt{40\sqrt{2}+57}\)
\(\sqrt{29-12\sqrt{5}}-\sqrt{12\sqrt{5}+29}\)
Tính:
\(a)E=\sqrt{\left|12\sqrt{5}-29\right|}-\sqrt{12\sqrt{5}+29}\\ b)\sqrt{\left|40\sqrt{2}-57\right|}-\sqrt{40\sqrt{2}+57}\)
Tính:
\(\sqrt{5-\sqrt{3-\sqrt{29-12\sqrt{5}}}}\)
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)\(\sqrt{2 +\sqrt{5-\sqrt{13+\sqrt{48}}}}\)
\(\sqrt{5}-\sqrt{3-\sqrt{29-12\sqrt{5}}}=\sqrt{5}-\sqrt{3\sqrt{\left(\sqrt{20-3}\right)^2}}\)
\(\sqrt{\sqrt{5}-\sqrt{3-\sqrt{29-6\sqrt{20}}}}\)
\(\sqrt{6+2\sqrt{5-\sqrt{13+\sqrt{48}}}}\)
\(B=-\sqrt{x}\left(\sqrt{x}-1\right)\)
Tính \(B\) biết \(x=\sqrt{\sqrt{5}-\sqrt{3-\sqrt{29-12\sqrt{5}}}}\)
Tính kĩ giúp mk
đừng làm tắt ạ
