h) \(\dfrac{2x-2\sqrt{x}+2}{x\sqrt{x}+1}\)
i)\(\dfrac{x-3\sqrt{x}+2}{x-\sqrt{x}}\)
k) \(\dfrac{x+7\sqrt{x}+12}{x-9}\)
l) \(\dfrac{x+\sqrt{x}-2}{x-2\sqrt{x}+1}\)
giải chi tiết hộ mình với ạ !!!
g: \(\dfrac{\sqrt{x}+3}{x\sqrt{x}+27}=\dfrac{1}{x-3\sqrt{x}+9}\)
h: \(\dfrac{2x-2\sqrt{x}+2}{x\sqrt{x}+1}=\dfrac{2}{\sqrt{x}+1}\)
i: \(\dfrac{x-3\sqrt{x}+2}{x-\sqrt{x}}=\dfrac{\sqrt{x}-2}{\sqrt{x}}\)
k: \(\dfrac{x+7\sqrt{x}+12}{x-9}=\dfrac{\sqrt{x}+4}{\sqrt{x}-3}\)
i: \(\dfrac{x+\sqrt{x}-2}{x-2\sqrt{x}+1}=\dfrac{\sqrt{x}+2}{\sqrt{x}-1}\)
