Question

\(\left(x-\dfrac{2}{3}\right)^3=\dfrac{1}{27}\)

Answer 1

`(x-2/3)^3=1/27`

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

`x-2/3=1/3`

`x=1/3+2/3=3/3=1`

Answer 2

`(x-2/3)^3 = 1/27`

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

`=> x - 2/3      = 1/3`

`=> x              = 1/3 + 2/3`

`=> x             = 1`

Answer 3

\(\left(x-\dfrac{2}{3}\right)^3=\dfrac{1}{27}\)

\(\left(x-\dfrac{2}{3}\right)^3=\left(\dfrac{1}{3}\right)^3\)

\(\Rightarrow x-\dfrac{2}{3}=\dfrac{1}{3}\)

\(x=\dfrac{1}{3}+\dfrac{2}{3}\)

\(x=1\)

Vậy \(x=1\)

Answer 4

Answer 5

\(\left(x-\dfrac{2}{3}\right)^3=\dfrac{1}{27}\)

\(\left(x-\dfrac{2}{3}\right)^3=\left(\dfrac{1}{3}\right)^3\)

\(\Rightarrow x-\dfrac{2}{3}=\dfrac{1}{3}\)

             \(x=\dfrac{1}{3}+\dfrac{2}{3}\)

              \(x=1\)
