Question

1) Calcule as potências: a) (−5) 3 = b) (−1) 9 = c) (−1) 10 = d) (−2) 4 = e) (−2) 5 = f) (+5) 3 = g) (−10) 8 = h) (−10) 9 = i) (+3) 1 = j) (−3) 1 =

Answer 1

Resposta:Segue as contas abaixo na explicação

Explicação passo-a-passo:

a) (−5) 3 = -125 ou (-5).(-5).(-5)-->(+25).(-5)-->-125

b) (−1) 9 = -1--->(-1).(-1).(-1).(-1).(-1).(-1).(-1).(-1).(-1)--->-1

c) (−1) 10 = +1--->(-1).(-1).(-1).(-1).(-1).(-1).(-1).(-1).(-1).(-1)--->+1

d) (−2) 4 = +16--->(−2).(−2).(−2).(−2)--->(+4).(+4)--->+16

e) (−2) 5 = -32--->(−2).(−2).(−2).(−2).(−2)--->(+4).(+4).(-2)-->(+16).(-2)--->-32

f) (+5) 3 = +125 ou (+5).(+5).(+5)-->(+25).(+5)-->+125

g) (−10) 8 = +100000000 ou (−10).(−10).(−10).(−10).(−10).(−10).(−10).(−10)--->+100000000

h) (−10) 9 = -1000000000 ou (−10).(−10).(−10).(−10).(−10).(−10).(−10).(−10).(−10)--->-1000000000

i) (+3) 1 = +3

j) (−3) 1 =-3
