Calcule as potências b)2⁷c)29⁰d)7¹e)(-6)³f)-6³g)(-⅓)⁴h)(8/5)³i...

Explicação passo-a-passo:

b)2⁷ = 2.2.2.2.2.2.2 = 128

c)29⁰ = 1

d)7¹ = 7

e)(-6)³ = (-6).(-6).(-6) = - 216

f) - 6³ = - 6.6.6 = - 216

g) (-⅓)⁴ = (-1/3).(-1/3).(-1/3).(-1/3) = 1/81

h) (8/5)³ = (8/5).(8/5).(8/5) = 512/125

i) 3,3² = 3,3.3,3 = 10,89

j) 7⁻² = (1/7)² = (1/7).(1/7) = 1/49

k) (5/2)⁻³ = (2/5)³ = (2/5).(2/5).(2/5) = 8/125

l) (-9)⁻² = (1/9)² = (1/9).(1/9) = 1/81
