解方程:9(x-1)^2=1/81
解方程:9(x-1)^2=1/81

解方程:9(x-1)^2=1/81
9(x-1)^2=1/81
3(x-1)=±1/9
x-1=±1/27
x=1±1/27

9(x-1)^2=1/81
(x-1)²=1/729
x-1=±1/27
x1=28/27, x2=26/27

9(x-1)^2=1/81
(x-1)^2=1/729
x-1=1/27或x-1=-1/27
x=28/27或 x=26/27

9(x-1)²=1/81
3²(x-1)²=(1/9)²
3(x-1)=±1/9
x-1=±1/27
x=1±1/27
x1=28/27
x2=26/27

(x-1)^2=1/81*1/9
(x-1)=1/27或-1/27
所以X=28/27或X=26/27
