Explicación paso a paso:

Lorena,

Aplicamos propiedaes operacionales de logaitmos

       $log(x  + 1) - log(x - 1) = 3\\ \\ log\frac{x+  1}{x-1} =3\\ \\ \frac{x+1}{x-1} =10^3\\ \\ x+1=(x-1)*10^3\\ \\ x + 1 =10^3x -10^3\\ \\ 1+10^3=10^3x - x\\ \\ 1+10^3=x(10^3-1)\\ \\ 1001=999x\\ \\ x=\frac{1001}{999} \\ \\ x=1,002002002...$

Answer 2

Respuesta:

x = 1001/999 = 1,002

Explicación paso a paso:

log(x + 1) = log(x - 1) + 3

log(x + 1) - log(x - 1) = 3

log ($\frac{x+1}{x-1})$ = log1000

$\frac{x+1}{x-1}$ = 1000

x + 1 = 1000(x - 1)

x + 1 = 1000x - 1000

x - 1000x = -1000 - 1

-999x = -1001

x = -1001/-999

x = 1001/999

x = 1,002
