Answer 1

Explicação passo-a-passo:

a) - 7² = - 49

b) (-5)²= +25

c) - 2⁵= - 32

d) (-2)⁵= - 32

e) - (-3)⁴= - (+81)= - 81

f) - (-3)³= - (- 27)= +27

g) (2/5)³= 8/125

h) (-2/5)-⁵= (- 5/2)⁵= - 3125/32

i) (-1/2)⁴= + 1/16

j) 150⁰= 1

k) 6-²= (1/6)²= 1/36

l) (8/5)-³= (5/8)³= 125/512

m) (- 2/3)³= - 8/27

n) (13/9)¹= 13/9

o)(-2/5)-² = (- 5/2)²= + 25/4
