its true! lol, it was my mistake, i forgot the change t^1/2 -> t^-1/2 thank you!

i have 1/2 (dt/ sqrt t) so 1/2 t^(3/2) / (3/2) then sqrt t / 3 then sqrt (e^2x+3)^3 / 3 its not the solution, it may be sqrt (e^2x+3)

yes, t=e^2x + 3 but still nothing

Homework Statement Integrate e^2x / SQRT [(e^2x) + 3)] Homework Equations The Attempt at a Solution i know the solution, is: SQRT [(e^2x) + 3] but i have no idea why. Please I need help thank you
