This is correct. Wolfram has just simplified it a bit.

Try taking (x+1)^(3/2) out as a factor and re-arrange.
5. u=x
du/dx= 1
dv/dx= (x+1)^1/2
v= 2/3 (x+1)^2/3

then u do:

UV - INTEGRAL V(du/dx)dx

right? so why do i get the wrong answer?

still doesn't make sense, i'm sorry.

i'm using

that formula....argh, i'm gertting annoyed.
9. thanks for persevering with me guys,
