a) \(\left(x-\frac{1}{2}\right)^2=0\)
\(x-\frac{1}{2}=0\)
\(x=\frac{1}{2}\)
b) (x - 2)2 = 1
x - 2 = 1 hoặc x - 2 = - 1
x = 3 hoặc x = 1
c) (2x - 1)3 = - 8
2x - 1 = - 2
2x = - 1
x = \(\frac{-1}{2}\)
d) \(\left(x+\frac{1}{2}\right)^2=\frac{1}{16}\)
\(x+\frac{1}{2}=\frac{1}{4}\) hoặc \(x+\frac{1}{2}=-\frac{1}{4}\)
\(x=-\frac{1}{4}\) hoặc \(x=-\frac{3}{4}\)
