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 ;

A big thank you to South India from North India! I love the fact that every state has it's own accent of speaking English and I can actually guess you belong from South. Thanks a ton!

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. 🙏

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.

@BobRossinspiredpainter 2 года назад

Amazing trick!! I learned a little of this in an online platform to some understanding, but not knowing the table I had to do it each time. This is great! I literally tried watching a different one before this and the tutorial was incorrect based on what I learned before and what I am seeing here.

@vipulupadhyay897 Год назад

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

@karthik_1306 3 года назад
