Answer 1

a- 1/32
b-1/125
c- 4
d- 1296
e- 3/2³
f- 4096
g- 5/3²
h- 243
i- 7

Answer 2

Você deve usar uma propiedade de potência, que diz ;

A^-p=1/A^p

a)2^-5=> 1/2^5=> 1/32
b)5^-3=> 1/5^3=> 1/125
c)(1/2)^-2=> 1/1/2^2=>1/1/4=>1*4/1=>4
d)6^-4=> 1/6^4=> 1/1296
e)(2/3)^-3=> 1/2/3^3=> 1/8/27=> 1*27/8=>27/8
f)4^-6=> 1/4^6=> 1/4096
g)(5/3)^-2=> 1/5/3^2=> 1/25/9=> 1*9/25=>9/25
h)3^-5=>1/3^5=> 1/243
i)(1/7)^-1=>1/1/7^1=>1*7/1=> 7

Espero ter ajudado
