Answer 1

${\huge{\mathfrak{\orange{\fcolorbox{red}{green}{\underline{ansWer}}}}}}$

Given :

$= (( (\frac{ - 1}{ \: \: 3} ) {}^{2} ) {}^{2} ) {}^{1}$

Solution :

$= (( (\frac{ - 1}{ \: \: 3} ) {}^{2} ) {}^{2} ) {}^{1}$

$\implies \: ({a}^{m}) {}^{n} = a {}^{mn}$

$= ( \frac{ - 1}{3} ) {}^{2 \times 2 \times 1}$

$= (\frac{ - 1}{3} ) {}^{4}$

$= \frac{( - 1) {}^{4} }{ {(3)}^{4} }$

$= \frac{1}{81}$
