Question

Se faz junto ou separado cada um??

Answer 1

Resposta:

$\log _3\left(2x+1\right)>\log _3\left(4-x\right)\quad :\quad \begin{bmatrix}\mathrm{Solucao:}\:&\:1<x<4\:\\ \:\mathrm{Notacao\:intervalo}&\:\left(1,\:4\right)\end{bmatrix}$

Explicação passo-a-passo:

$\log _3\left(2x+1\right)>\log _3\left(4-x\right)$

$2x+1>4-x\quad \mathrm{e}\quad \:4-x>0$

$2x+1>4-x\quad \mathrm{e}\quad \:4-x>0\quad :\quad 1<x<4$

$1<x<4$
