Explicação passo-a-passo:

8)

a) 7^2= > 49

b) 4^2=> 16

c)2^5=> 2x2x2x2x2 = 32

d) 8^1= > 8

e) 9^0= > 1

f)(-9)^2=> (-9). (-9) = + 81

g)(-5)^3=>  (-5).(-5).(-5) = -125

h)(-1)^7=> (-1).(-1).(-1) .(-1).(-1).(-1) .(-1) = -1

i)(-15)^1=> -15

j)(-10)^0= > 1

k)(+3)^4= > (+3).(+3).(+3).(+3)= + 81

l)(-1)^56=> +1 expoente par  

m)(-10)^5=> (-10).(-10).(-10).(-10).(-10) = -100000

9)

a)2^5=>  2x2x2x2x2 = 32

b)(-2)^5= > (-2).(-2).(-2).(-2).(-2)=> -32

c)-2^5= > -32

d)2^4=> 2x2x2x2 = 16

e)(-2)^4=>  (-2).(-2).(-2).(-2)= +32

f)-2^4= > -32

g)-(-3)^4=>  -[(-3).(-3).(-3).(-3)] = -[+81]= -81

h)-(-5)^3=>  -[(-5).(-5).(-5)] = -[-125]= +125

i)-(+2)^6=​> -[(+2).(+2).(+2).(+2).(+2).(+2)] = -[+64] = -64
