# Integral of 1 / 1 + sqrt [x]

Hi, I am a newbie here and would like to ask you stg. integral of 1 / 1 + sqrt [x]

I used chain rule and used x = u^2 is that true?

Thanx for any replies

Do the substitutions that neutrino and morphism suggested.

Can't you use integration by parts?

I'm doing this in my head and not fully awake, so I could be wrong.
we have 1/(1+sqrt(x)) You can use the substitution that you've shown.
u^2=x
2udu=dx
So we end up with 2u/1+u
remember you can substitute more than once....
