Question

1- Calcule as seguintes potencias:

a) (0,5)-³ =
b) (2/3)-¹ =
c) (1/10)²=
d) (2,5)² =
e) (1/2)³ =
f) (-0,2)⁵=
​

Answer 1

Resposta:

a) (0,5)-³= (5/10)-³= (1/2)-³= (2/1)³= 2³= 8

b) (2/3)¹= 2/3

c) (-1/10)²= + 1/100

d)(2,5)²= (25/10)²= (5/2)²= 25/4

e)(1/2)³= 1/8

f)(-0,2)^5= ( - 2/10)^5= (-1/5)^5= - 1/3125
