Answer 2

Question :-

• Simplify $\sqrt[4]{(81)^{-2}}$

Answer :-

• $\sqrt[4]{(81)^{-2}} \: = \sqrt[4]{ \bigg(\frac{1}{81} \bigg) {}^{2} }$

• $\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: \sqrt[4]{ \bigg( \frac{1}{81 \times 81} \bigg)}$

• $\: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt[4]{ \bigg( \frac{1}{9 \times 9\times 9 \times 9} \bigg)}$

• $\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{9}$

Answer = $\huge\frac{1}{9}$
