power. Siri's is an infinite Siri's of the form some a N X to the end, where in is a non negative into your so by non negative that just means that it's could be any positive. Integer could also be zero so it can start at zero and then it's infinite. So it'LL go all the way up to infinity you. In some cases it could start at one thatjust corresponded a case where a subzero was zero. So that can happen but infinite power. Siri's air just infinite sums that look like this again, and his constant constant just means that it does not depend on X.
