\(x:\left(-\dfrac{1}{3}\right)^2=-\dfrac{1}{3}\\ \Rightarrow x=\left(-\dfrac{1}{3}\right).\left(-\dfrac{1}{3}\right)^2\\ \Rightarrow x=\left(-\dfrac{1}{3}\right)^3\)
\(x:\dfrac{1}{9}=-\dfrac{1}{3}\\ x=-\dfrac{1}{3}.\dfrac{1}{9}\\ x=-\dfrac{1}{27}\)
\(x:\left(\dfrac{-1}{3}\right)^2=\dfrac{-1}{3}\)
\(x:\dfrac{1}{9}=\dfrac{-1}{3}\)
\(x\) \(=\left(\dfrac{-1}{3}\right).\dfrac{1}{9}=\dfrac{-1}{27}\)
