Question

log (x-1)+3=log(x+1)​

Answer 1

Respuesta:

log(x+1)=log(x-1)=3Resolveremos por parte ya que tiene dos signo =log(x+1)=3log(x+1)=log(10)³x+1=1000x=999Ahora el segundo loglog(x-1)=3log(x-1)=log(10)³x-1=1 

log10(x+3)+log10(x)=1→log10((x+3)(x))=1→log10x2+3x=1→101=x2+3x 0=x2+3x−10→0=(x+5)(x−2)→x=−5,x=2.
