ME AJUDEM POR FAVOR!

Answer 1

Resposta:Segue as contas abaixo na explicação

Explicação passo-a-passo:

a) (−9) 2--->(−9).(−9)--->81

b) (−5) 3--->(−5).(−5).(−5)---->-125

c) (−1) 7---->(−1).(−1).(−1).(−1).(−1).(−1).(−1) --->-1

d) (−15) 1--->-15

e) (−10) 0--->1

f) (7)−2--->(1/7).(1/7)--->1/49

g) (2)−4--->(1/2).(1/2).(1/2).(1/2)---->1/16

h) (−3) −2--->(-1/3).(-1/3)--->1/9

i) (5)−3--->(-1/5).(-1/5).(-1/5)--->-1/125

j) (−2) 4--->(−2).(−2).(−2).(−2)--->16
