The representation is not possible in general.

Suppose we have the following sum of exponentials function of time:
S(t) = e^(a1*t) + e^(a2*t) + e^(a3*t) + ... + e^(an*t)

Where the a's are constant.

First question is: is it true that we can express S(t) as:
S(t) = n * e^(A*t), where A is a constant?

If so, how can we compute A?

Thanks!
