Question

integrate 1/(1+x)^3 dx from x=0 to infinity

Answer 1

\[\Large\int_0^\infty\frac1{(1+x)^3}dx\]

Answer 2

What is your problem?

Answer 3

what are your thoughts?

Answer 4

It is a problem in integrating or problem in substituting?

Answer 5

solve it step by step
and integrate 1/(x*lnx) dx from x=0 to infinity
integrate 1/(x+3)^(3/2) dx from x=3 to 4
and find the interval or state they diverge

Answer 6

if you convert to exponential form, you can use the formula of integration i wrote down.. are you familiar with that conversion?
