Question

Математика, срочно. Нужна помощь!!!!

Answer 1

Ответ:

$log_{0.2}(x - 1) = 4$

$x - 1 = {0.2}^{4}$

$x - 1 = {( \frac{2}{10} )} ^{4}$

$x - 1 = {( \frac{1}{5} )}^{4}$

$x - 1 = \frac{ {1}^{4} }{ {5}^{4} }$

$x - 1 = \frac{1}{625}$

$x = \frac{1}{625} + 1$

$x = \frac{1 + 625}{625}$

$x = \frac{626}{625}$
