Question

`( x -1/2 )^3 = 1/8`

Answer 1

Lời giải:

$(x-\frac{1}{2})^3=\frac{1}{8}=(\frac{1}{2})^3$

$\Leftrightarrow x-\frac{1}{2}=\frac{1}{2}$

$\Leftrightarrow x=\frac{1}{2}+\frac{1}{2}=1$

Answer 2

`( x -1/2 )^3 = 1/8`

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

`=> x - 1/2 = 1/2`

`=> x = 1/2 + 1/2`

`=> x = 2/2 `

`=> x = 1`
