How can I make these series equal to each other?

  1. Hi,

    I'm trying to see if there is an operation or set of operations I can perform on S1 so that it equals S2. I've just been going in circles and it seems I just don't have enough knowledge of how factorials behave in series to crack this. Any hints would be much appreciated.

    Hope this makes sense.

    You can't. The first term of s2 is (-1)! which is infinite.
  4. Thanks for the reply; would it help to set k=1 for both series, and deal with the first terms separately? And forgot to mention that S1=e.

    S1 = (1+a)b. I suggest you try to understand what this is about.
  6. Sorry, you mean understand the problem or the equation in your post? I know that S1 equals (1+a)^b as well as e. But I guess there isn't a similar closed form of S2.

    As for the problem, this is just some "fun" exploration of numbers I made up.
