    Summation to infinity involving gamma

    How do I solve this :

    1+(gamma)+ (gamma^2)/(2!)+(gamma^3)/3!+....

    The answer given is e^gamma.

    Btw,how do I post questions using mathematical symbols(gamma,set notation etc.)? I'm new here. Thanks a lot!

    The Maclaurin series for f(x) = e^x is \sum_{n=0}^{\infty} \frac{x^n}{n!}.

    We know the series converges to f(x), so your question amounts to recognizing that your series is simply f(\gamma)
