Question

${8}^{x} = 0.25$
​

Answer 1

Resposta:

$8 {}^{x} = 0,25$

$2 {}^{3x} = 2 {}^{ - 2}$

$3x = - 2$

$x = - \frac{2}{3}$

$x = 0,666...$

Answer 2

Resposta:

S = { - 2/3}

Explicação passo-a-passo:

${8}^{x} = 0.25$

${8}^{x} = \frac{1}{4}$

$({ {2}^{3} })^{x} = \frac{1}{ {2}^{2} }$

${2}^{3x} = {2}^{ - 2}$

$3x = - 2$

$x = - \frac{2}{3}$

S = {- 2/3}
