1. ### why is L . C .M of rational numbers not posible?

... r/s. p/q = (ps/rq) (r/s) This property does not exist for integers, and hence we talk of least common multiple for integers...

use sub t=x^2 +1 dt = 2x.dx so integral is, ∫1/t.dt = ln(t) + C and t = x^2 +1 so = ln(x^2 +1) + C Now you do the other one!
