Answer 1

Olá!!!

Resoluçao!!!

1)

= 8-²
= 1/8²
= 1/8 • 1/8
= 1/64

2)

= 5-¹
= 1/5¹
= 1/5

3)

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

4)

= 1/2-³
= 2/1³
= 2³
= 2 • 2 • 2
= 8

5)

= ( - 3 )-³
= ( - 1/3 )³
= ( - 1/3 ) • ( - 1/3 ) • ( - 1/3 )
= ( + 1/9 ) • ( - 1/3 )
= - 1/27

6)

= 1/2^-5
= 2/1^5
= 2^5
= 2 • 2 • 2 • 2 • 2
= 4 • 4 • 2
= 16 • 2
= 32

Espero ter ajudado!!
