Giải pt: \(2\sqrt[4]{27x^2+24x+\frac{28}{3}}=1+\sqrt{\frac{27}{2}x+6}\)
giải pt : \(\frac{36}{\sqrt{x-2}}+\frac{4}{\sqrt{y-1}}=28-4\sqrt{x-2}-\sqrt{y-1}\)
2. Giải PT:
a) \(\frac{9x-7}{\sqrt{7x+5}}=\sqrt{7x+5}.\)
b) \(\sqrt{4x-20}+3\sqrt{\frac{x-5}{9}}-\frac{1}{3}\sqrt{9x-45}=4.\)
c) \(2x-x^2+\sqrt{6x^2-12x+7}=0.\)
d) \(\left(x+1\right)\left(x+4\right)-3\sqrt{x^2+5x+2}=6.\)
giải hệ pt \(\frac{1}{\sqrt{x}}+\frac{y}{x}=\frac{2\sqrt{x}}{y}+2\)
\(16x^4-24x^2+8\sqrt{3-2y}-3\)
Giải Ph Trình
\(\frac{1}{2}\sqrt{x-1}-\frac{3}{2}\sqrt{9x-9}+24\sqrt{\frac{x-1}{64}}=-17\)
\(3x-7\sqrt{x}+4=0\)
\(-5x+7\sqrt{x}+12=0\)
giải Pt:
\(\frac{36}{\sqrt{x-2}}+\frac{4}{\sqrt{y-1}}=28-4\sqrt{x-2}-\sqrt{y-1}\)
giải pt \(\frac{\sqrt{14}-\sqrt{7}}{1-\sqrt{2}}x+\frac{2}{\sqrt{7}-\sqrt{5}}=\frac{\sqrt{15}-\sqrt{5}}{\sqrt{3}-1}x\)
Giải các pt sau
a) \(\sqrt{\frac{5x-4}{x+1}}=2\)
b)\(\frac{\sqrt{5x-4}}{\sqrt{x+1}}=2\)
giải pt \(\frac{1}{\sqrt{x}}+\frac{1}{\sqrt{2x-3}}=\sqrt{3}\left(\frac{1}{\sqrt{4x-3}}+\frac{1}{\sqrt{5x-6}}\right)\)
