Answer 1

Resposta:

a) (+7)² = 7 × 7 = 49

b) (+4)² = 4 × 4 = 16

c) (+3)² = 3 × 3 = 9

d) (+5)³ = 5 × 5 × 5 = 125

e) (+2)³ = 2 × 2 × 2 = 8

f) (+3)³ = 3 × 3 × 3 = 27

g) (+2)⁴ = 2 × 2 × 2 × 2 = 16

h) (+2)⁵ = 2 × 2 × 2 × 2 × 2 = 32

i) (-5)² = - 5 × - 5 = 25

j) (-3)² = - 3 × - 3 = 9

k) (-2)³ = - 2 × - 2 × - 2 = - 8

l) (-5)³ = - 5 × - 5 × - 5 = - 125

m) (-1)³ = - 1 × - 1 × - 1 = - 1

n) (-2)⁴ = - 2 × - 2 × - 2 × - 2 = 16

o) (-3)³ = - 3 × - 3 × - 3 = - 27
