Question

Write a c++ program to find the sum of the series 1+n+n^2+...n^m
(where n and m take user-specified values)

Answer 1

The reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. Activity series of some of the more common metals, listed in descending order of reactivity.

Explanation:

Set variable “denominator” initially to 1.

Set variable “denominator” initially to 1.Set variable “sum” to be initially equal to 0.

Set variable “denominator” initially to 1.Set variable “sum” to be initially equal to 0.Add 1/denominator^denominator to the sum. That is, calculate sum += 1/denominator^denominator. I believe you need to use the pow() function for this.
