Rút gon \(T=3\sqrt{2}+2\sqrt{3}-\sqrt{18}+\sqrt{28-16\sqrt{3}}\)
Rút gon biểu thức sau: \(\sqrt{18\left(\sqrt{2}-\sqrt{3}\right)^2}\)
Rút gọn
B=\(\left(2\sqrt{18}+\sqrt{50}-7\sqrt{\frac{1}{2}}\right).\sqrt{2}-5\sqrt[3]{54}.\sqrt[3]{2}\)
rút gọn biểu thức
E=2\(\sqrt{3}\)+3\(\sqrt{27}\)-\(\sqrt{300}\)
F=3\(\sqrt{2}\)+4\(\sqrt{18}\)
G=2\(\sqrt{3}\)-4\(\sqrt{27}\)+5\(\sqrt{48}\)
H=(3\(\sqrt{50}\)-5\(\sqrt{18}\)+3\(\sqrt{8}\))\(\sqrt{2}\)
rút gọn biểu thức
A=2015+\(\sqrt{36}\)-\(\sqrt{25}\)
B=5\(\sqrt{8}\)+\(\sqrt{50}\)-2\(\sqrt{18}\)
C=\(\sqrt{27}\)-2\(\sqrt{12}\)-\(\sqrt{75}\)
D=\(\sqrt{12}\)+\(\sqrt{27}\)-\(\sqrt{48}\)
rút gọn các câu sau
a,\(2\sqrt{18}-4\sqrt{50}+3\sqrt{32}\)
b,\(\sqrt{\left(\sqrt{8}-4\right)^2}+\sqrt{8}\)
c,\(\sqrt{14-6\sqrt{5}}+\sqrt{6+2\sqrt{5}}\)
rút gon biểu thức
\(A=\frac{2}{\sqrt{7}-\sqrt{6}}-\sqrt{28}+\sqrt{54}\)
Rút gon:
\(\frac{\sqrt{1+2\sqrt{5\sqrt{\text{ 7 }}-13}}-\sqrt{\sqrt{\text{ 7 }}-2}}{\sqrt{3-\sqrt{\text{ 7 }}}}-\sqrt{\frac{2}{3-\sqrt{5}}}\)
Rút gon: \(\dfrac{2\sqrt{2}}{\sqrt{2\sqrt{2}+1}+11}-\dfrac{\text{2}\sqrt{2}}{\sqrt{2\sqrt{2}+1}-1}\)
