\(\left(-3\right)^2.\left(\dfrac{1}{3}\right)^2:\left[\left(\dfrac{-2}{3}\right)+1-1\dfrac{1}{3}\right]\)
\(=9.\dfrac{1}{9}:\left[\left(\dfrac{-2}{3}\right)+1-\dfrac{4}{3}\right]\)
\(=9.\dfrac{1}{9}:\left(-1\right)\)
\(=1:\left(-1\right)=-1\)
\(\left(-\dfrac{2}{5}\right)^2.\left(1,08-\dfrac{2}{25}\right)^{10}:\dfrac{4}{7}\)
\(=\dfrac{4}{25}.\left(\dfrac{27}{25}-\dfrac{2}{25}\right)^{10}:\dfrac{4}{7}\)
\(=\dfrac{4}{25}.1:\dfrac{4}{7}\)
\(=\dfrac{4}{25}.\dfrac{7}{4}=\dfrac{7}{25}\)
