Answer 1

Resposta:

Explicação passo-a-passo:

Calcule as potências:

A) -7²

= - 49

B) (-5)²

= + 25

C) -2⁵

= - 32

D) (-2)⁵

= - 32

E) -(-3)⁴

= - (81)

= - 81

F) -(-3)³

= -(-27)

= +27

G) ( 2)³

( 5) =

(2/5)^3 = 8/125

H) ( -2) -³

( 5 ) =

= (- 5/2)^3

= -125/8

I) ( -1 )⁴

( 2 ) =

= 1/2^4

= 1/16

J) 150⁰

= ​1
