Question

Calcule as potências ​

Answer 1

a)

(-5)^3=(-5).(-5).(-5)=(+25).(-5)=-125

b)

(1/3)^4=(1/3).(1/3).(1/3).(1/3)=

(1/3)^4=(1/81)

c)

(0,2)^2=(2/10)²=2.2/10.10=4/100=1/25

d)

(-4/9)^1= (-4/9)

e)

(2,1)^3=(2,1).(2,1).(2,1)=9,261

f)

(-12,8)^0= 1

espero ter ajudado!

bom dia !

Answer 2

Resposta:

a) (-5)^3 = (-5)×(-5)×(-5)= -125

b)(1/3)^4 = 1/3×1/3×1/3×1/3 = 1/81

c) (0,2)^2 = (0,2)×(0,2) = 0,04

d) (-4/9)^1 = -4/9

E) (2,1)^3 = 2,1 x 2,1 x 2,1 = 9,261

f) (-12,8)^0 = 1
