c) 1\9 . 1\9 . 1\9 =
d) (-5) . (-5) . (-5) . (-5)=

Answer 1

Resposta:

A) 8⁷

B) 2,4⁶

C) 1/9³

D)(-5)⁴

Answer 2

a) (-2) ⋅ (-2) ⋅ (-2) ⋅ (-2) ⋅ (-2) = (-2)^5 = -32

b) 1/7 ⋅ 1/7 ⋅ 1/7 = (1/7) ^3 = 1/343

c) 81 ⋅ 81 ⋅ 81 = 81 ^3 = 534441

d) (-10) ⋅ (-10) = (-10)^2 = 100

e) 10 ⋅ 10 ⋅ 10 ⋅ 10 = 10 ^4 = 10000
