Question

calcula as potências negativas das frações abaixo:
a)(1/2)-¹
b)(-1/3)-²
c)(-1/4)-¹
d)(2/3)-³
e)(-5/3)-³
f)(1/11)-²
g)(3/5)-³
h)(3/2) elevado a -4

Answer 1

Explicação passo-a-passo:

a) (1/2)-¹= (2/1)¹= 2

b) ( -1/3)-²= (-3/1)²= (-3)²= +9

c) (-1/4)-¹= (-4/1)¹= (-4)¹= -4

d) (2/3)-³= (3/2)³= 27/8

e) (-5/3)-³= (- 3/5)³= - 27/125

f) (1/11)-²= (11/1)²= 11²

g) (3/5)-³= ( 5/3)³= 125/27

h) (3/2)-⁴= (2/3)⁴= 16/81
