Answer 1

Answer:

$\frac{1}{81}$

Step-by-step explanation:

Using the rule of exponents

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Evaluating from the inside parenthesis outwards

$(-\frac{1}{3}) ^{2}$ = - $\frac{1}{3}$ × - $\frac{1}{3}$ = $\frac{1}{9}$ , then

$(\frac{1}{9}) ^{-2}$ = $\frac{1}{9^{-2} }$ = 9² = 81 , then

$(81)^{-1}$ = $\frac{1}{81}$
