Answer 1

Answer:

Program to find the sum of the series (1/a + 2/a^2 + 3/a^3 + … + n/a^n)

Given two integers

a and

n. The task is to find the sum of the series 1/a + 2/a2 + 3/a3 + … + n/an.

Examples:

Input: a = 3, n = 3

Output: 0.6666667

The series is 1/3 + 1/9 + 1/27 which is

equal to 0.6666667

Input: a = 5, n = 4

Output: 0.31039998
