\((x - 1)^3 = \frac{1}{8}\)

Answer 1

\(\left(x-1\right)^3=\dfrac{1}{8}\)
\(\left(x-1\right)^3=\left(\dfrac{1}{2}\right)^3\)
\(x-1=\dfrac{1}{2}\)
\(x=\dfrac{1}{2}+1\)
\(x=\dfrac{1}{2}+\dfrac{2}{2}\)
\(x=\dfrac{3}{2}\)
Vậy `x=3/2`

Answer 2

`( x - 1)^3 = 1/8`

` ( x - 1)^3 = ( 1/2)^3`

` x - 1 = 1/2`

`x = 1/2 + 2/2`

`x = 3/2`
