a) (-6/8)² =
b) (+3/5) ⁴=
c) (-6/10)³ =
d) (-10/20)² =
e) (+10/25)² =
f) (-3/2)² =
g). (-1/3)⁶=
i). (+2/3)⁶=​

Answer 1

Resposta:

A) (-6/8)² = 36/64 = 0,56

B) (+3/5)⁴ = 81/225 = 0,36

C) (-6/10)³ = -216/1000 = -0,21

D) (-10/20)² = 100/400 = 0,25

E) (+10/25)² = 100/265 = 0,16

F) (-3/2)² = 9/4 = 2,25

G) (-1/3)⁶ = -1/729 = 0

I) (+2/3)⁶ = 64/729 = 0.08
