Thread: 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:

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

Show it is the same as what? I suspect the problem is asking you to simplify the expression. Something is very wrong in the terminology or there is something more to this question.
