Se log x (1/8)= 3 então:

a) x = 2

b) x = − 2

c) x = 1/2

d) x = −1/2

e) x= 1/4

Answer 1

log x (1/8)= 3

x³ = (1/8)

x³ = (1/2)³

x = 1/2 ✓

Answer 2

Oie, Td Bom?!

>>> Resposta: Opção C.

$log_{x}( \frac{1}{8} ) = 3$

$\frac{1}{8} = x {}^{3}$

$x {}^{3} = \frac{1}{8}$

$x = \sqrt[3]{ \frac{1}{8} }$

$x = \frac{1}{2}$
