# Math Help - Log equation

1. ## Log equation

Hello

ln ( (e^x+1) / (x^3 + x^2) ) needs to be verified

So here's what I got:

= ln ( (e^x+1) / (x^3 + x^2) )

= ln (e^x+1) - ln (x^3 + x^2)

= (x+1) ln e - ln ((x^2(x+1))

-can't get past this point.

What do you mean by "verified?"

We can go a few more steps:
$= (x+1) ln(e) - ln (x^2(x+1))$

$= (x+1) ln(e) - ln (x^2) - ln(x+1)$

$= (x+1) ln(e) - 2ln (x) - ln(x+1)$

and since $ln(e) = 1$,

$= (x+1) - 2ln (x) - ln(x+1)$

3. I guess verify here means show that it is the same as?
