one doubt sir highest power of 12 in 60! is what? is it 4*3 = 12 means i need to consider highest power of 4 which is 28 so highest power of 12 in 60! is "28" am i right sir?
Just a quick tip for you, if you're asking us to watch a specific video because you have explained something in that, for eg: 0!, just provide the link of that video in the description. I hope you're not expecting us to find the video ourselves. Thankyou!
Sir, in que find the highest power of 18 in 60! Ans is 28. There we just found the power of 3 bt in the last question u said that find the power of 8. By why....... Why we can't write 146is the highest power of 8
But sir ek que arise hua h sir. Jab apn 60! Me 12 ki highest power nikalege to wo sir 12^28 aarahi hai joki sir 11, 10 inse bhi jyada hai sir. Ar ye apne bataya tha sir ki jese jese number increase honge unki power kam hogi. To sir kha galti kar raha hu me . Please reply dijie ga sir..
Listen the fact is only true for prime no. and 12 is not a prime no. Further if you going ahead you notice that power of 15 will be 14( which is of 5 ), further more power of 25 will be still 14. Because just think if you have asked to make twelves by 56 times 2, and 28 times 3 then, what will you do is you take 28 times 2 multiply by 28 times 2 multiply by 28 times 3, Means ( 2x2x3 ) to power 28 gives 12 to power 28.
Sir, after each video, could you please provide a pdf of questions so that we can strengthen the concept furthermore. Thanks for such amazing videos ❤️❤️❤️
I browsed through a lot of Udemy courses, but the content you are providing is just amazing... U r nurturing a lot us without taking a single penny... U have a special spot reserved in my heart... 😻😻😻
Thanks a lot sir!! I cannot tell you how much you are helping me out! Students get confused when there are so many channels available and sometimes get caught up in the web of so many of paid courses. You are a complete package sir,thanku for working so hard for teaching us free and without any confusion.
Bestest! I go to TIME institute they are very good in teaching but they are not this much great, Rodha are really teaching from very basics and going till CAT level. I really appreciate. Really we are very lucky to find them as they charge nothing.
Thank you so much ❤sir i was discouraged while solving the questions from book 📕bcuz they seem very hard, but now really really i m getting each n every thing. This is my 4th day of preparation. 🌺🤞
I didn't understand the calculation 12×7×4×3×2×2 , in the very first question in this video. How to calculate that result from the numbers we have taken in prime basis?
@cobratatesmindset1for finding number of factors we just need to multiply all the prime numbers, now 6 can be written as 2×3 means we got one more pair of 2 and 3 similarly we will break down every number and collect all the prime numbers , that's how they got powers
Sir, you are the kind of teacher whose class i would have never missed in school, college, coaching. Such a mastery in a subject is difficult to come by in teachers nowadays. Thankyou so much for making these videos! Really grateful to you.
Sir I am sorry for telling this .... I am complete begginer to aptitude , your first four videos have helped me a lot.... In coming days I will watch all your videos without fail and even without missing even a second. You made me to study sir. Pls help me with this. If I crack elitmus examination I will be happy I will earn more money. Thanks for the lecture sir. Doubt happened here 3:20 Here the problem is I cant understand the way you group the numbers and the powers accordingly Reply with your email id..............................
It's like a mathematical illusion, Try an experiment, just break any number into its factors, you'll always get the factors in prime no. viz. Factors of 20 will be 2x2x5 Factors of 210 will be 2x3x5x7 now notice on these factors 2,3,5,7 is a prime no. So for making calculation easier, we can break any number into factor or multiple of a prime no. Also for your 2nd question, Break all the numbers in simple and simple form, so if you'll break 2 into, you'll get 2x1 4 into 2, you'll get 2x2 6,then 2x3 8, then 2x2x2 10, then 2x5 12,then 2x2x3 14,then 2x7 Now counts all the 2 which gives 11 times two. That's why he wrote 2 to power 11
Sir or if anyone can help me please reply..............in the begining we calculated factorial for 15 right?? so there why are we adding power + one to all the numbers??
The concept is not clear.... the teaching method is vague. Your voice irritates us. Secondly the shortcut used for calculating the factors of 15! is not understandable.
Thank you sir for the wonderful lecture! i am gonna crack CAT 2024 easily!🎉 i have made a study group for cat aspirants, details are in the about section of my channel.
Yes.He has only touched the concepts. We need to build upon that. But when I saw questions of CAT on prime numbers, they were difficult. Let's hope for best.
are you able to understand the concept of how to find highest power using factors bcoz by sir's method answer of 25! is 22 but actual ans is 23 if you understand plss explain

Sir
Numbers ki 4th video direct factorials hai kya
Sir while finding of factorial of 15
You have taken all prime no. Out
i.e. 2*3*5*7*11*13

sir where can i get the quizzes...for practice..
Sir, in que find the highest power of 18 in 60! Ans is 28. There we just found the power of 3 bt in the last question u said that find the power of 8. By why.......
Why we can't write 146is the highest power of 8
Because 2 is the only prime no. Factor of 8 . 2x2x2 so you have to calculate factor on base of 2 factors

.
For "number of factors" @ 5:49 why? Power + 1 ??
Because it the trick we have to add one to the power
That's because we also consider power 0 ( ie. prime no. to the power 0 = 1) so to include 0 we need to add 1.
For understand in early watch this Video ruclips.net/video/GU2t11iDFrI/видео.html
In 33:06 the adding up of factors will make 145 i guess and not 146
Add the number 1 also bro. Its 146
Sound quality is really poor. Teaching is fantastic though
Sir can you plz explain how, the highest power of 2 in 150! Is 146,as mine it's coming out to me 145., do revert sir.

6,then 2x3

Now counts all the 2 which gives 11 times two. That's why he wrote 2 to power 11
