Question

2) Calcula as potências:
a) 2³ =
b)(-4)³=
c)(-5)-²
d) 4-⁴=​

Answer 1

Assunto:  Potencias.

2^3 = 8

(-4)^3 = -64

(-5)^-2 = (-1/5)^2 = 1/25

4^-4 = (1/4)^4 = 1/256

Answer 2

¡Hey!!

Resposta:

$a) \: {2}^{3} = 2 \times 2 \times 2 = 8$

$b) \: ( { - 4})^{3} = - 4 \times - 4 \times - 4 = - 64$

$c) \: ( { - 5})^{2} = - 5 \times - 5 = 25$

$d) \: {4}^{ - 4} = 4 \times 4 \times 4 \times 4 = - 256$
