Program to input the value of x and n and print the sum of series 1+x+x^2+x^3+x^4..x^n | Practical

In this video, I have covered up the practical 5 of CBSE Class 11 Computer Science with Python. Write a program to input the value of x and n and print the sum of the following series: 1+x+x2+x3+x4+ ............xn. I have described 3 different methods that can be used for the problem with their programming codes. Method 1: #Write a program to input the value of x and n and print the sum of the following series: #1+x+x^2+x^3+x^4+ ............x^n print(" Write a program to input the value of x and n and print the sum of the \n") print(" following series: 1+x+x^2+x^3+x^4+ ............x^n \n") x = int(input("Enter value of x:")) n=int(input("Enter value of n:")) s=0 for i in range(n+1): k=x**i s=s+k print(" Sum of the series: 1+x+x^2+x^3+x^4+ ............x^n \n") print(" with x:",x,"and n:",n,"is=",s) Method 2: #Write a program to input the value of x and n and print the sum of the following series: #1+x+x^2+x^3+x^4+ ............x^n print(" Write a program to input the value of x and n and print the sum of the \n") print(" following series: 1+x+x^2+x^3+x^4+ ............x^n \n") x = int(input("Enter value of x:")) n=int(input("Enter value of n:")) s=1 k=1 for i in range(n): for j in range(i): k=k*x s=s+k print(" Sum of the series: 1+x+x^2+x^3+x^4+ ............x^n \n") print(" with x:",x,"and n:",n,"is=",s) Method 3: #Write a program to input the value of x and n and print the sum of the following series: #1+x+x^2+x^3+x^4+ ............x^n import math print(" Write a program to input the value of x and n and print the sum of the \n") print(" following series: 1+x+x^2+x^3+x^4+ ............x^n \n") x = int(input("Enter value of x:")) n=int(input("Enter value of n:")) s=0 for i in range(n+1): k=math.pow(x,i) s+=k print(" Sum of the series: 1+x+x^2+x^3+x^4+ ............x^n \n") print(" with x:",x,"and n:",n,"is=",s) To learn python full course watch: https://www.youtube.com/watch?v=-eZ9aGK4NmY&list=PLuND5JsayY-xzEYTExVVsHSnV3RyU7_Og To learn Class XI Computer Science: https://www.youtube.com/watch?v=6QVBMuWIBrk&list=PLuND5JsayY-ypqFFFqQyD_H5y5MdIflMc fb page : https://www.facebook.com/computerguruhub/ Author on fb: https://www.facebook.com/sknager Telegram Channel: https://t.me/computerguruhub Telegram Group: https://t.me/computerguruhub1 if you want video on any particular topic you can comment or contact. #computerscience #cbse #computerscienceclass11 #python #class11computerscience #pythonprogramming #cbsepythonclass11 #pythonclass11 #class11 #class11pythoninhindi #pythonclass12 #class11python #pythonforclass11 #pythontutorial #advantagesofpython #csforclass11 #codipymohit #pythonpracticalprogramming #ipforclass11 #practical #class11pythonchapter1 #pythontutorialforbeginners #cbsepythonboardexampapers #class12pythoninhindi #completepythoncourse #cs #xi #cbseclass11computerscience #computerscienceclass11cbse #sumitaaroraclass11 #pythoninhindi #class11pythoncbse #computerscienceforclass11 #pythonforbeginners #pythonclass11cbse #classxi #sumitkumarnager #computerguruhub
