`(x-1/3)^3=27`
`<=> (x-1/3)^3=3^3`
`<=> x-1/3 = 3`
`<=> x= 3 +1/3`
`<=>x= 9/3 + 1/3`
`<=>x= 10/3`
vậy `x=10/3`
\(\Leftrightarrow\left(x-\dfrac{1}{3}\right)^3=3^3\Leftrightarrow x-\dfrac{1}{3}=3\Leftrightarrow x=\dfrac{10}{3}\)
\(\left(x-\dfrac{1}{3}\right)^3=27\)
\(\Rightarrow\left(x-\dfrac{1}{3}\right)^3=3^3\)
\(\Rightarrow x-\dfrac{1}{3}=3\)
\(\Rightarrow x=3+\dfrac{1}{3}\)
\(\Rightarrow x=\dfrac{9}{3}+\dfrac{1}{3}\)
Vậy \(x=\dfrac{10}{3}\)
