Question

calcule as potências abaixo

a)(-0,5)-¹=

b)(1,5)-²=

c)-(-6)-¹=

d)5-⁴=

e)-5³=

f) (-1/4)-²=​​

Answer 1

a) (-0,5)-1 = (-5/10)-1 -> 10/-5 > -2

b) (1,5)-2 = (15/10)-2 = 10.10/15.15 = 4/9

c) -(-6)-1 = -(1/-6) = -6

d) 5-4 = 1/5.5.5.5 = 1/625

e) -5.-5.-5 = - 125

f) (-1/4)-2 = 4.4/-1.-1 = 16/1 = 16
