When will we get the assignment in Assamese language?
Sir you approach for the last question of the video is not at all correct. The concept applied is wrong. m saying this because 3^(4n+1) gives the unit digit to be 3,3^(4n+2) gives the unit digit to be 9 etc etc... for example 3^5 (5 can be written as 4n+1) gives 243 so the unit digit is 3 and so on...
