Hi, how would you simplify this summation. I have the steps, but I don't see it. Can someone explain it? =]
Sum from n = 0 to infinity: [(lambda*e^t)^n]/n!
The next step is: e^(lambda*e^t)
so you notice in your question, what is in place of x is lambda*e^t, so you just replace x with that in the above formula, so you see on the left it is equal to e^(lambda*e^t)
