\(\sqrt{x-2-4\sqrt{x-2}}+\sqrt{x+7-6\sqrt{x-2}=5}\)

Giúp em câu này với ạ!

b) \(x^2+8x-3\) = \(2\sqrt{x\left(8+x\right)}\)

c)\(\sqrt{\dfrac{x^2+x+1}{x}}+\sqrt{\dfrac{x}{x^2+x+1}}=\dfrac{7}{4}\)

\(x+y+z+35=2\left(2\sqrt{x+1}+3\sqrt{y+2}+4\sqrt{z+3}\right)\)

b) \(x^2+8x-3=2\sqrt{x\left(8+x\right)}\)

c)\(\sqrt{x-2}+\sqrt{x+1}+\sqrt{2x+3}=6\)
