dijawab no 2-5 ya.. makasih

2.3(x - 1 )/x = 2/x-2
   3x - 3/x =2/x - 2
   3x² -9x + 6 = 2x
   3x² -11x +6 =0
   (3x -2)(x - 3)=0
    x =2/3 & x =3
3.x=√ab⁻²
   x/a = √ab⁻²/a
         = [tex] (ab^{-2})^{1/2} [/tex]
         =[tex] a^{1/2} [/tex]b⁻¹/a
         =[tex] a^{-1/2} [/tex]/b
         =1/b√a
