Explicação passo-a-passo:

a)7²=49

b)9°=1

c) - 10^6= - 1000000

d) (-0,3)⁴=+ 0,0081

e) (-3/2)²= +9/4

f)(-3/4)³= - 27/64

g) (1,9)²= 3,61

h)20-¹= 1/20

i) (-6)-¹= (- 1/6)¹= -1/6

j)11-²= (1/11)²= 1/121

k) 2^-6= (1/2)^6= 1/64

l) (2/3)-³= (3/2)³= 27/8

m)(1/3)-⁴= (3/1)⁴= 3⁴= 81

n)(4/3)-²= (3/4)²= 9/16
