Question

Помогите решить уравнение

Answer 1

$log_{ frac{1}{ sqrt{2} } }(2 + 2x) = - 4 \ log_{ frac{ sqrt{2} }{2} }(2 + 2x) = - 4 \ 2 + 2x = {( frac{ sqrt{2} }{2}) }^ {-4} \ 2 + 2x = {( frac{2}{ sqrt{2} } )}^{4} \ 2 + 2x = { sqrt{2} }^{4} \ 2 + 2x = {2}^{2} \ 2 + 2x = 4 \ 2x = 4 - 2 \ 2x = 2 \ x =1$
