Step-by-step explanation:

 \bf \underline{Solution-} \\

 \bf{ \sqrt[4]{(81 {)}^{ - 2} }  }\\

 \bf =   \sqrt[4]{ \bigg( \frac{1}{81} \bigg) ^{2}  }  \\

  \bf =  \sqrt[4] {\left\{{ \bigg( \frac{1}{9}  \bigg) ^{2} }\right\} ^{2} } \\

 \bf =  \sqrt[4]{ \bigg( \frac{1}{9}  \bigg) ^{4} }  \\

 \bf  =  \bigg( \frac{1}{9}  \bigg) ^{4 \times  \frac{1}{4} }  \\

 \bf =  \frac{1}{9}  \: \\

 \bf \underline{Hence \:  the  \: value  \: of \:  \sqrt[4]{(81 {)}^{ - 2}  } } \: is \:  \frac{1}{9} . \\
