Bài 1: 

a: ĐKXĐ: \(x\ge\dfrac{3}{2}\)

Bài 4:

\(a,A=\dfrac{x-1}{\sqrt{x}\left(\sqrt{x}-1\right)}=\dfrac{\left(\sqrt{x}-1\right)\left(\sqrt{x}+1\right)}{\sqrt{x}\left(\sqrt{x}-1\right)}=\dfrac{\sqrt{x}+1}{\sqrt{x}}\\ P=A:B=\dfrac{\sqrt{x}+1}{\sqrt{x}}\cdot\dfrac{x-1}{\sqrt{x}+1}=\dfrac{x-1}{\sqrt{x}}\\ b,P\sqrt{x}=m-\sqrt{x}+x\\ \Leftrightarrow x-1=m-\sqrt{x}+x\\ \Leftrightarrow m=\sqrt{x}-1\)

\(\left(x-36\right):18=12\)

\(x-36=12x18\)

\(x-36=216\)

           \(x=216+36\)

           \(x=252\)

\(K\)\(nha!!!\)

x-36:18=12

=>x-2=12

=>x=12+2

=>x=14

Vậy x=14

nhanh giúp mình ạ

giúp mình với ạ
