Question

produto de fatores iguais na forma de uma só potência e calcule o resultado.
a) (-2) ⋅ (-2) ⋅ (-2) ⋅ (-2) ⋅ (-2) =
b) 1/7 ⋅ 1/7 ⋅ 1/7 =
c) 81 ⋅ 81 ⋅ 81 =
d) (-10) ⋅ (-10) =
e) 10 ⋅ 10 ⋅ 10 ⋅ 10 =

Answer 1

Explicação passo-a-passo:

a) (-2)⁵ = -32

b) (1/7)³ = 1/343

c) (81)³ = 531.441

d) (-10)² = 100

e) (10)⁴ = 10.000

Answer 2

$a)( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) = \\ - (2 \times 2 \times 2 \times 2 \times 2) \\ {2}^{5} \\ - 32$

$b) \frac{1}{7} \times \frac{1}{7} \times \frac{1}{7} = \frac{1 \times 1 \times 1}{7 \times 7 \times 7} = \frac{1}{343}$

$c)81 \times 81 \times 81 = \\ {8}^{3} \\ 531441$

$d)( - 10) \times ( - 10) = \\ 10 \times 10 \\ 100$

$e)10 \times 10 \times 10 \times 10 = \\ {10}^{4} \\ 10000$
