When I uese matlab to solve the Equation, it always cannot work, it returns NaN. This puzzled me a few days. The Equation as follows.

sum(P(k)*x^(k^(alpha)))=0.9995, where 0<k<infty and alpha=15.

I know k^alpha is very large, but how to make this can solve is really hard for me. Thanks!

what is P(k)?

Is x in the range -1 <= x <= 1, or can abs(x) be greater than 1 ?
