    Remember this 3 lines
    1.Last Digit of a num =0,1,5,6 ; Unit Digit will be 0,1,5,6 (For any power)
    2.If Last Digit of a num =4,9 and Power is odd ; Unit digit will be 4,9 ; if Power is even Unit digit will be 6,1
    3.if Last digit of a num =2,3,7,8 ; Devide the power by 4,
    if Remainder=0 ; Unit Digit will be 6 for 2 & 8 ; 1 for 3 & 7 ; if R !=0 Unit Digit will be (last Digit)^R ;

      what does it mean? please explain it better!
      start from 1) If the last no is 1 the cyclicity is?
      2) And in case the last digit of 1 remainder is 0 then the unit digit is?
      Please explain sir.

      They are basically square, cube etc,
      So 1² or 1*(to the power anything)willl always be one.
      Same goes with 0.
      1. 1
      2. 0

    Dear ma'am please pinned the comment about when l = 3,7 or 9 the unit digit is 1 instead of 0 👍
    For example : 143^124
    By dividing 124 by 4 the remainder is 0. In this case we can take 3⁴=81. So the unit digit is 1. 🙏

    Great work mam ! But if someone don't want to remember the table then only :-
    1.divide the power by four
    2.last digit of no ^remainder
    You get your unit digit .
    Note:- in case of zero remainder :
    Last digit of no ^4 gives you correct unit digit

    I just watched your video, and it completely messed up my calculations! You made a fundamental mistake by saying that the unit digit is zero when the last digit is 3, 7, or 9. That’s just wrong-the unit digit should be one, not zero. This kind of misinformation is unacceptable for students preparing for exams. It wasted my time and threw off my progress. You really need to correct this ASAP because wrong information like this is seriously harmful. That said, your teaching style and other content are really good, but this mistake needs immediate attention!

    Hence we can directly write "6" as unit digit of 2016^(2015)

      Give the no. 1 2 3 0 to the cyclicity of 4 and as per reminder we get unit digit also for o reminder.
      Ex. 2^64. R=0, so unit digit 6
      Ex 7^64. R=0. So unit digit 1
      7^ 45. R=1. Unit digit is 7
      For cyclisity of 2= 1 0
      Ex 4^30. R=0. So unit digit 6
