\(\sqrt{16\sqrt{8\sqrt{4}}}\)
\(\frac{4\sqrt{x}}{2+\sqrt{x}}+\frac{8\sqrt{x}}{4-x}:\left(\frac{\sqrt{x}-1}{x-2\sqrt{x}}-\frac{2}{\sqrt{x}}\right)\)
\(\sqrt[x]{2}\)+\(\sqrt[y]{2}\)+\(\sqrt[z]{2}\)=2336 hoi x y z la bao nhieu ?
Cho mình hỏi \(\sqrt{4}\),\(\sqrt{9}\),\(\sqrt{16}\)
Đơn giản hóa (\(\dfrac{1}{2}\))\(\dfrac{-1}{4}\)
A. -16 B. -\(\sqrt{2}\) C. -\(\dfrac{1}{16}\) D.\(\dfrac{1}{256}\) E.\(\sqrt{2}\)
Đơn giản hoá \(\left(\dfrac{1}{2}\right)^{\dfrac{-1}{4}}\)
A) -16 B) -\(\sqrt{2}\) C) -\(\dfrac{1}{16}\) D) -\(\dfrac{1}{256}\) E) \(\sqrt{2}\)
\(a,\sqrt{x}-1=4
\)
\(b,\sqrt{\left(x-1\right)^4=16}\)
Tính
\(\frac{2\sqrt{3}}{\sqrt{2}+\sqrt{2}+\sqrt{3}}+\frac{2-\sqrt{3}}{\sqrt{2}-\sqrt{2}-\sqrt{3}}\)
\(\frac{\sqrt{2}}{2\sqrt{2}+\sqrt{3}+\sqrt{5}}+\frac{\sqrt{2}}{2\sqrt{2}-\sqrt{3}-\sqrt{5}}\)
\(\frac{\sqrt{2}+\sqrt{3}+\sqrt{6}+\sqrt{8}+4}{\sqrt{2}+\sqrt{3}+\sqrt{4}}\)
\(\frac{\left(5+2\sqrt{6}\right)\left(49-20\sqrt{6}\right)\sqrt{5-2\sqrt{6}}}{9\sqrt{3}-11\sqrt{2}}\)
\(\frac{\frac{\sqrt{2+\sqrt{3}}}{2}}{\frac{\sqrt{2+\sqrt{3}}}{2}-\frac{2}{\sqrt{6}}+\frac{\sqrt{2+\sqrt{3}}}{2\sqrt{3}}}\)
Mọi người giúp em với!!!!! một trong 5 câu đó cũng đc!!!! Ai tốt thì giúp em hết luôn nha!!!!! Em cảm ơn !!!!!
Tính tích:
\(A=\frac{3}{\sqrt[2]{2}}x\frac{8}{\sqrt[2]{3}}x\frac{15}{\sqrt[2]{4}}x\frac{24}{\sqrt[2]{5}}x....x\frac{899}{\sqrt[2]{30}}\)
