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 ;

Please edit your video that in the case of l=3 or 7 or 9 if remainder is zero then unit digit will be 1, not 0

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!

[@vishalmundhe7682]

Hi

[@SatwinderSingh_007]

Yeah because her accent is South Indian

[@julfuquarkhan3481]

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. 🙏

Are you preparing for government jobs? Jean

[@BobRossinspiredpainter]

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.

[@Supriya100kar]

You are an excellent teacher! Thank you very much 🙂

[@godcolor9722]

No offense but i m just curious Aap abhi kaunsi job krrhi hai?

Thankyou ma'am for amazing explanation!🙏Just need to correct unit digit as 1 in case of l = 3,7,9

[@gpavankumargpavankumar3545]

Yes bro.. You are right

[@swetachoudhary6155]

Thank you for telling

[@somdeepbose8466]

Yes....This had me wondering for a couple of minutes

[@shashangkipgen6065]

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.

[@estherchishi5254]

@@shashangkipgen6065 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

[@arunaraju4966]

thanks for the explanation but please make the correction- * if the remainder is zero and l = 3,7,9 the unit digit is 1 * 6^anything always ends by 6 ; also, 5^anything always ends in 5

I have a simple trick Last two digit of power divided by 4 Answer will be unit digit to the power reminder. For reminder 0 take 4.

Error:for digit 9 Solution:if units place is 9 and if the power of 9 is even then units digit will be 1 and if the power of 9 is odd then units digit will be 9

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

6^anything always ends by 6 so not only for 5 but also 6 has exception ..🤔

[@sanketsharma6885]

Yeah that's too an exception

[@avulaakshith770]

Yup yup agreee

[@venkatabrahmajipadala9830]

"0,1,5,6" All these are Exceptions. For all of them, there won't be any change. i.e., Units Digits will be 0,1,5,6 only.

[@arvindchaudhary6626]

It is basically not an exception but a fundamental property of 6 and 5.

Mam you made this topic very very easy for me... by the way I am a tenth grader and I really found it difficult to solve this question thanks alot mam....😍😍🥰🥰🤩🤩

[@kaviyak4620]

in the third sum, since the cyclicity for 6 is always 1, can't we directly write the unit digit as 6? Because for 5, we did it directly!

[@richhpalbarwar5882]

Ya

[@venkateshmannem9211]

Cyclic of 6 is always 6

Wrong concept for l=3,7,9 with r=0..in such case u.d will be 1..except this everything is correct

What if L=1? what is the cyclicity of 1? why it's no given in the table?

[@hanhlinhhotran121]

@@revanthkumarchiruvolu3503 for 1 to any power, the last digit is always going to be 1 so no trick there.

@@revanthkumarchiruvolu3503 for cyclicity is 1 only, any power to 1 unit digit will be 1 only

[@mayakhan8857]

For 33^6 ud is 9

[@renukaramachandran1898]

Unit digit when remainder is 0 concept is different.. Actually it will be the unit digit of the last cyclicity.. For eg 3^8 8/4=0 So unit digit will be that of last cyclicity that is unit digit of 4 in this case which is 1

[@karthik_1306]

Amazing Video.. :) In the last question: Don't you think that "every power of 6 also ends in 6 only", so the unit digit will be 6 only? Hence we can directly write "6" as unit digit of 2016^(2015)

[@badal3200]

Please tell is this method is correct or not 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
