P=\(\left(\frac{2\sqrt{x}}{9-x}+\frac{1}{3+\sqrt{x}}\right)\).\(\frac{x\left(3-\sqrt{x}\right)}{\sqrt{x}-2}\)

a, RG

b, tìm x để P=\(-\frac{1}{3}\)

giúp mik vs nha!

P=\(\left(\frac{\sqrt{x}-2}{x-1}-\frac{\sqrt{x}+2}{x+2.\sqrt{x}+1}\right):\left(\frac{2}{x^2-2x+1}\right)\)

a, RG

b,tìm x để P>0

c,tìm gt của P thì x=\(7-4\sqrt{3}\)

d,tìm max P

Mik gấp lắm!!! Giúp mik vs nhé!!!

Bài 1 : Rút gọn biểu thức

a, A=\(\sqrt{24+16\sqrt{2}}-\sqrt{24-16\sqrt{2}}\)

b, B=(\(\sqrt{3+\sqrt{5}}-\sqrt{3-\sqrt{5}}\))²

c, C=\(\sqrt{a+2\sqrt{a-1}}+\sqrt{a-2\sqrt{a-1}}\) với 1 < a < 2

d, D=\(\sqrt{\left(7+4\sqrt{3}\right)\left(a-1\right)^2}\)

e, T=(\(\sqrt{8+2\sqrt{7}}+\sqrt{8-2\sqrt{7}}\))(\(\sqrt{63}+1\))

Bài 2: Tìm điều kiện xác định của các biểu thức sau

a,\(\sqrt{-3x+2}\)

b,\(\frac{1}{\sqrt{x}-1}\)

c,\(\frac{-2}{\sqrt{x^2+6}}\)

d,\(\sqrt{\frac{1}{x^2+x-2}}\)

Bài 3:Cho biểu thức: P=\(\frac{\sqrt{x}}{\sqrt{x}-1}+\frac{3}{\sqrt{x}+1}-\frac{6\sqrt{x}-4}{x-1}\)

a, rút gọn P

b, Tìm x để P<\(\frac{1}{2}\)
