Question

calcule as potencias abaixo
a)8³
b)(-4)⁵
c) 3-⁴
d) (²/³)-³
e) (-7)⁴
f) (-10)⁰
g) (1,2)³
h) ( ³/⁵)⁴ ​

Answer 1

al 8^3= 8×8×8=512

b) (-4)^5= (-4)×(-4)×(-4)×(-4)×(-4)= -1'024

c) -3^4 = -(3×3×3×3)= -81

d) (2/3)^3= 2^3/3^3= 8/27

e) (-7)^4 = 2'401

f) (-10)^0 = 1

g) (1,2)^3 = 1,728

h) (3/5)^4= 3^4/5^4= 81/625
