    Could someone please give me some guidance as to how to approach the following question.
    I tried using the radius of converge as that was what my previous lecture was based on but that didn't seem to help.
    Thanks

    The sum of the series for exp x is obviously bigger than any single term (when x > 0). So pick a term that dominates x^n and squeeze.

    Edit: to be clear, it doesn't have anything to do with radius of convergence - a simple comparison argument suffices.

    I considered doing this but surely for small values of n the summation isn't always higher then x^n?

    Oh I just realised that the sum is up to infinity. Never mind. Thankyou for your help
