Giải PT.
a)\(\sqrt[3]{x+4}-\sqrt[3]{x-6}=1\)
b) \(\sqrt[3]{x^2}-8\sqrt[3]{x}=20\)
c) \(\frac{x\sqrt[3]{x}-1}{\sqrt[3]{x^2}-1}-\frac{\sqrt[3]{x^2}-1}{\sqrt[3]{x}+1}=4\)
Giải pt:
1) x - 2\(\sqrt{x - 1}\) = 16
2) \(\sqrt{1\:-\:x}\) - \(\sqrt{x - 3}\) = 0
3) \(\sqrt{x - 4}\) + 2 = 7
4) x - \(\sqrt{x - 2\sqrt{x\:-\:1}}\) = 0
5) \(\sqrt{x - 2}\) - \(\sqrt{x^2 - 2x}\) = 0
6) \(\sqrt{3\:-\:2\sqrt{2}}\) - \(\sqrt{x^2 + 2x\sqrt{2}+2}\) = 0
1)giải pt \(x^3-9x^2+6x-6-3\sqrt[3]{6x^2+2}=0\)
2) giải hệ pt \(\int^{\sqrt{x}\left(1+\frac{3}{x+3y}\right)=2}_{\sqrt{7y}\left(1-\frac{3}{x+3y}\right)=4\sqrt{2}}\)
giải pt ạ
\(\sqrt{x+2+2\sqrt{x+1}}+\sqrt{x+10-6\sqrt{x+1}}=2\sqrt{x+2-2\sqrt{x+1}}\)
giải pt \(\sqrt{x+2\sqrt{x-1}}+\sqrt{x-2\sqrt{x-1}}\ge\dfrac{3}{2}\)
giải hệ pt \(\int^{x+y+xy=5}_{\left(x+1\right)^3+\left(y+1\right)^3=35}\)
giải pt \(\sqrt{\left(3+2\sqrt{2}\right)^x}+\sqrt{\left(3-2\sqrt{2}\right)^x}=6\)
help me!!!
Rút gọn: \(\sqrt{\left(\sqrt{3}+1\right)2^{ }}-\sqrt{4-2\sqrt{3}}\)
Giải PT: \(\dfrac{3}{5}\). \(\sqrt{25x-50}\) - \(\sqrt{x-2}\) = 6
Giải các PT sau:
\(a,\sqrt{x-2\sqrt{x-1}}-\sqrt{x-1}=1\)
\(b,\sqrt{x+3-4\sqrt{x-1}}+\sqrt{x+8+6\sqrt{x-1}}=1\)
\(c,\sqrt{x+\sqrt{2x-1}}+\sqrt{x-\sqrt{2x-1}}=\sqrt{2}\)
\(d,\sqrt{x+\sqrt{6x-9}}+\sqrt{x-\sqrt{6x-9}}=\sqrt{6}\)
1. Giải pt:
\(\sqrt{x^2-2x+1}-\sqrt{x^2-6x+9}=10\)
2. Giải pt:
\(\sqrt{x+2\sqrt{x-1}}=3\sqrt{x-1}-5\)
