 \bigg[  \bigg(\bigg( -\frac{1}{3}  \bigg)^{2} \bigg) ^{ - 2}  \bigg]^{ - 1}

Multiplying the powers \sf{[(x)^{m}]^{n}=x^{mn}}

 \bigg( -  \frac{1}{3}  \bigg) ^{2 \times ( - 2) \times ( - 1)}  \\  \\ \rightarrow \bigg( -  \frac{1}{3}  \bigg) ^{4} \\  \\  \rightarrow  \bigg( -  \frac{ {1}^{4} }{ {3}^{4} } \bigg) \\  \\  \rightarrow \bigg( -  \frac{1}{81} \bigg) \\  \\   \:  \:  \:  \:  \:  \:  \:  \: \bigstar \:  \boxed{\bigg( -  \frac{1}{81} \bigg)}
