Answer 2

Answer:

9

Step-by-step explanation:

Using the rules of exponents/ radicals

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$

$(^m)^{n}$ = $a^{mn}$

$a^{\frac{m}{n} }$ ⇔ $\sqrt[n]{a^{m} }$

Thus

$(\frac{1}{27}) ^{\frac{1}{3} }$ = $\frac{1}{27^{\frac{1}{3} } }$ = $\frac{1}{\sqrt[3]{27} }$ = $\frac{1}{3}$

$(\frac{1}{81}) ^{-\frac{3}{4} }$

= $\frac{1}{81^{-\frac{3}{4} } }$

= $81^{\frac{3}{4} }$

= $(\sqrt[4]{81} )^3$ = 3³ = 27

Thus

$\frac{1}{3}$ × 27 = 9
