Choose the correct answer intsqrt(1+x^(2))dx is equal to

`x/2sqrt(1+x^(2))+1/2logabs((x+sqrt(1+x^(2))))+C`

`2/3(1+x^(2))^(3/2)+C`

`2/3x(1+x^(2))^(3/2)+C`

`(x^(2))/2sqrt(1+x^(2))+1/2x^(2)logabs(x+sqrt(1+x^(2)))+C`

`1/3e^(x^(3))+C`

`1/3e^(x^(2))+C`

`1/2e^(x^(3))+C`

`1/2e^(x^(2))+C`

`logabsx-1/2log(x^(2)+1)+C`

`logabsx+1/2log(x^(2)+1)+C`

`-logabsx+1/2log(x^(2)+1)+C`

`1/2logabsx+log(x^(2)+1)+C`
