Answer 1

Olá.

A
$3^{-2}$
$\dfrac{1}{3^2}$

$\boxed{\dfrac{1}{9}}$

B
$5^{-3}$
$\dfrac{1}{5^3}$

$\boxed{\dfrac{1}{125}}$

C
$-2^{-3}$
$\dfrac{1}{-2^3}$

$\boxed{\dfrac{1}{-8}}$

D
$\pi^{-3}$
$\boxed{\dfrac{1}{\pi^3}}$

E
$-4^{-2}$
$\dfrac{1}{-4^2}$

$\boxed{\dfrac{1}{16}}$

F
?

G
$\dfrac{2}{5}^{-3}$
$\dfrac{5^3}{2^3}$

$\boxed{\dfrac{125}{8}}$

H
$\dfrac{3}{2}^{-3}$

$\dfrac{2^3}{3^3}$

$\boxed{\dfrac{8}{27}}$

I
$\dfrac{-3}{4}^{-5}$

$\dfrac{4^5}{-3^5}$

$\boxed{\dfrac{1024}{-243}}$

J
$0,5=\frac{1}{2}$
$\dfrac{1}{2}^{-5}$

$\dfrac{2^5}{1}$

$\boxed{32}$

I
$1,2=\frac{6}{5}$
$\dfrac{6}{5}^{-3}$

$\dfrac{5^3}{6^3}$

$\boxed{\dfrac{125}{216}}$
