Resposta:

Explicação passo a passo:

CALCULE AS POTENCIAS

A) (2/3)^3 = 2/3 . 2/3 . 2/3

= 8/27

B) (4/7)^2 = 4/7 . 4/7

= 16/49

C) (7/5)^2 = 7/5 . 7/5

= 49/25

D) (1/3)^2 = 1/3 . 1/3

= 1/9

E) ( 5/3)^2 = 5/3 . 5/3

= 25/9

F) (7/30)^0 = 1

G) (9/5)^1 = 9/5

H) (2/3)^3 = 2/3 . 2/3 . 2/3

= 8/27

I) (1/5)^3 = 1/5 . 1/5 . 1/5

= 1/125

J) (1/2)^2 = 1/2 . 1/2

= 1/4
