Answer 1

Olá!!!

Resolução!!!

e)

= ( - 5 )-³
= ( - 1/5 )³
= ( - 1/5 ) • ( - 1/5 ) • ( - 1/5 )
= - 1/125

f)

= ( 2/3 )-²
= ( 3/2 )²
= ( 3/2 ) • ( 3/2 )
= 9/4

g)

= ( - 8/5 )-³
= ( - 5/8 )³
= ( - 5/8 ) • ( - 5/8 ) • ( - 5/8 )
= - 125/512

h)

= ( - 3/5 )-³
= ( - 5/3 )³
= ( - 5/3 ) • ( - 5/3 ) • ( - 5/3 )
= - 125/27

i)

= ( + 1/2 )-⁴
= ( + 2/1 )⁴
= 2⁴
= 2 • 2 • 2 • 2
= 16

j)

= ( - 1/3 )-³
= ( - 3/1 )³
= ( - 3 )³
= ( - 3 ) • ( - 3 ) • ( - 3 )
= - 27

Espero ter ajudado!!
