Exercise 7 - due at 11:59:00 PM on 09/21/2021 You may include your solution for Problem 4 in a comment at the end of your program for Problems 1 and 2. 1. Write a program to print the sum of the first 200 even mumbers (0 included). Sample Output: The sum of the first 200 even numbers is : 39800 2. Write a program to find the nth power of a number x. That is, read in a real number x and an integer n, and caclulate x raised to n. You may assume that neither x nor n will be 0. n will always be a positive number. You need to use a loop and accumulation for this. You are not allowed to use cmath functions. You do not have to accoutn for overflow (as in, if the values overflow, it's ok). Sample Output 1: Enter x: 2 Enter the exponent n: 7 2^7 = 128 Sample Output 2: Enter x: 10.75 Enter the exponent n: 5 10.75^5 = 143562.932617 3.
