\(-\dfrac{2}{3^3}:0,\left(3\right)+\left(\dfrac{2}{3}\right)^2\)
\(=\dfrac{-2}{27}:\dfrac{1}{3}+\dfrac{4}{9}\)
\(=\dfrac{-2}{9}+\dfrac{4}{9}=\dfrac{2}{9}\)

`(-2/3)^3 \div 0,(3) + (2/3)^2`
`= (-2/3)^3 \div 1/3 + (2/3)^2`
`= (-2/3)^3 * 3 + (2/3)^2`
`= (2/3)^2 * (-2/3 * 3 + 1)`
`= 4/9 * (-2+1)`
`= 4/9 * (-1)`
`= -4/9`
