[@divyakn955]

Sir just bcoz of ur this depth explanation I started liking quant . Thank u soooooooooo very much SIR .

[@abhijitteli5849]

Hello gaurav sir... I am science graduate student... From 2016, I always watches study iq videos... I really like quality of videos... I have a one suggestion for you sir... Please bring videos on computer programming languages, like C, C++, JAVA, PYTHON, RUBY, R, PERL etc... Private classes like niit take 1 - 1.5 lakhs to teach this languages... So students from poor background can't afford this fee and they deprived from this crucial education... Please sir... Please sir give me a reply... Please do it... Thank you...

[@omprakashsharma2945]

Best videos I have called across. Plz bring videos of arithmetic, geometry, algebra, trigonometry, pnc, probability

[@sanjaynathvyas693]

Way of your teaching is so impressive...salute sir😍

[@sumitoza1776]

Ultimate teaching.... Thank you very much sir. Please take complete course... As per your convenience.... Way you teach is really awesome... And speed is Supreme... Thanks a lot sir...

[@manishmamgain11]

After that teach arthematic plese!!!

[@chandrashekharmuktapur5585]

You didn't explained divisibility of 17 sir. You forgot to explain in lecture video 3

[@kareemka5030]

chandrashekhar muktapur Hi, it will be covered in 7th video.. thanks for reminding..

[@chandrashekharmuktapur5585]

Kareem Ka Thank you your reply. Your content is very good sir.

[@namamishawasthi]

I think it is same as divisibility rule of 7, I have checked 17's power cycle and unit digits are same as in case of 7

[@khushboodubey2647]

sir your teaching is awesome ...Thanku sir ..please sir provide more these type of videos which is helpful in entrance exam.

[@jyotivyas4719]

Fabulous!! Thanks for existing 🙏

[@abhishekpandey5423]

Bahut shi sir....mujhe ye question nhu bante the....ab se banne lage.....great

[@anandkanagaraj4089]

This is related to divisibility by 11! 1) I've taken this number (N) = 83487699 2) I've grouped it into two so that each group has 4 digits (we have a flexibility to group into any number in case of 11) 3) The difference between two groups = (7699-8348) = -649 which is actually divisible by 11 4) But, the whole number is not divisible by 11 5) Is it because of the negative difference sir? In that case, what is the possible to way to find a solution sir?

[@funwithphysicss]

Group it into odd numbers, like groups of 1,3,5,7,9...etc as powers of 10 showing +,-1 remainder are alternative

[@auroshispanda1764]

You can't group the number into groups of 4, cause 4 is even.. You have to group it into groups of 1 or 3 or 5 or 7 or 9 etc..

[@AbidTech]

Bhut accha sir , Thank you

[@Ashishopinion]

Well explained!!!!!

[@reshutiwarid7832]

Ur way of explanation is very good sir.... plz explain GS imp questions....

[@ash_engineering]

[@antonysamuel5298]

Found it extremely useful thanks a lot continue the gud work 👍👍👍

[@gsmcompny]

Sir is same apply for fractions also? say (243•48)^4.68 for such qsn how to solve..

[@pratitigarg]

really helpful, thankyou..

[@akashnigam5488]

you haven't taught rule for 17

[@visheshbaliyan7286]

Perfect please continue arithmetic after it

[@ankitverma4753]

sir what is the method to solve when in remainder is 0 in case of 2,3,7,8 please explain.

[@AbdulBasittrading]

Last digit into 1 aur kya

[@shibanisabnis790]

Wonderful video. I have a doubt. What if the Q is 3^32 Here there wont be a remainder so how do we get the answer?

[@gayatribagri4962]

Fabulous...way of teaching....

[@barathrajmanivannan9896]

Sir what is the last digit of 2 power 240 Because we are getting 0 remainder Pls help me with this sir 9:30

[@adamrasheed257]

Wat abt 2 raise to 72???...If v divide 72/4 remainder is 0...But tats not supposed to be the last digit right?

[@dhruvghosh8826]

Ur way of teaching is coooollllll

[@yuvaraj8922]

If remainder of the power is 0. what will be the last digit then ??

[@namanlalpura5691]

Sir, you are just awesome 🔥

[@piyushvankar9238]

Sir what will be the unit's digit of 1273 power to 122!

[@swatipradhan8722]

Sir what to do if I get remainder 0 in any of the question.. What power I need to take?

[@gouravsawai8415]

2^0 means 2^4 thus last digit will be 6

[@shubhamavhad9269]

Sir is there any trick for finding out the last two digits of given no. With given power ??

[@kanhabhakti276]

What if we r getting power in term of factorial?

[@kartikjangid5462]

hi what would be the answer if the remainder is 0 for eg 12^12 the remainder is 0 so what about it

[@meghaseal2631]

Thanku sir...

[@kshitijdhopte3463]

What does he mean by Frequency?

[@dayanandkumar9052]

Superb job sir

[@Rajeshdhkd]

Very good lecture

[@sandhyagumary3997]

Sir what is the answer for 2 raised to the power 84? Or s when the the frequency is divided by the power and the remainder comes as zero? Then whats the last digit?

[@chintit_chidiya]

value where the cycle ends. 2^4 i.e 6.

[@krishnapalsingh9705]

After number system..... Please take word problem.

[@ShrutiGupta-zj1zj]

what if the power when divided by 4 leaves no reminder ..so that would be number raise to power 0 and answer would be one for each case?

[@abhishekmishrikoti8260]

if it is completely divisible take the 4th power like 2^4 last digit is 6 and 3^4 last digit is 1 and 7^4 last digit is 1 and 8^4 last digit is 6

[@rajalakshmip6178]

thank you sir...

[@mafia1000ism]

what if the power is a multiple of 4(power cycle) and the remainder is zero?

[@prajwalkatakhon7536]

Bruh seriously

[@adityaanand4496]

bro attend the lectures where ppl explain that 4 is an even number so last digit turns out to be 6 asshole

[@amandugar4229]

What if while dividing the power with the cycle or frequency, the remainder is zero? Then what would be the last digit?

[@vaibhavpatil7767]

1............Suppose last digit is 80 and we divide it by 4 then remainder is 0. therefore 8^0 = 1

[@soudipkhan8539]

What will Happen when Remainder =0 , how will we find the last digit ?.... As u said 2^R , 3^R.....

[@YogeshKumar-cq4rr]

R will become power cycle No. i.e 4/2 depending upon unit digit.

[@tajamulkhanday531]

i want to know what if power is completly divisible by its frequency then what will be its last digit for example (123453)^2345678765448. what will be the answer

[@mohitpant779]

7

[@ayush5349]

THANKYOU VERY VERY MUCH

[@deveshyadav1]

Best ever seen.

[@vihaan6459]

Where are other 3 lectures , pls send it’s link

[@jennifergnanaraj8360]

Sir, what about the power cycle of 4?

[@ayush5349]

BEST AND EASIEST

[@parinirwan4781]

Thank you sir

[@theclashers3405]

Can i know the name of sir who is teaching in this video

[@dheerajtiwari9827]

Sir what equipment you use to write

[@rizwaniqbal830]

You didn't cover Divisibility of 17 in last lecture

[@satviksood3892]

So the last digit and remainder is one and the same thing?

[@ankurrathi2314]

last digit and remainder when a number is divided by 10 is same thing

[@subhankardeysarkar6999]

Thank u Sir thank u

[@imbillu753]

Awesome

[@DHARMENDRAKUMAR-nq6sc]

sir g LCM air hcf bhee batana please

[@vihuraj1135]

Awesome❤️

[@vihuraj1135]

😂😂just reduce the number😂😂😂beauty of mathematics

[@backpackerpanda9674]

this is lecture 4 next is 6 where is 5

[@mahimanigam3475]

Sir what if the power is exactly divisible by 4 and remainder comes to 0

[@ineedspace760]

So use rule of indices A raised to 0 is 1

[@mahimanigam3475]

@@ineedspace760 okay thanks!

[@kushsagwadia1261]

what if we divide the power and remainder comes zero

[@AbdulBasittrading]

Last digit Into 1 will be ans
