Yes, that's correct too. In exams and in general, if the number is a "round" number like e⊃2/2, I would give the answer as e²/2=3.6945(approx.) because the latter is an approximation. This will give the exact value as the answer.

That is not a complex fraction in the sense of being a complex number (1.e., containing the square root of -1). As x-> 0, 1/(2+x) behaves like (1/2)[1/[1 + (x/2)] = (1/2)[1 - (x/2)] Subtract 1/2 from that, divide by x, and you have (-x/4)/x = -1/4 You could also use L'...
