🔴 √2 is Irrational - Proof by Contradiction || Number Systems - 3 || in HINDI for Class 9 NCERT

[@निःShabd]

Sir, why we not considered it as reducible in starting rather than irreducible..?

[@allinone-sy2wj]

Irreducible means co primes

[@Snow-w7o]

√2 = a/b where a and b are reducible so we reduce it and get p/q and therefore p and q do not contain any common factor other than 1 and therefore p and q are co-prime integers

[@mastu741]

Because if p/q is rational number then p,q must be co-prime numbers(according to rational number definition)

[@ankushchauhan5605]

gcd of p and q is 1.( Acc to def. Of rational number) We suppose √2 is rational It implies √2= p/q and it is irreducible .

[@Visiongenre]

Kyoki hame contradiction paida karna hai agar ham reducible do integer lete hain to contradiction hi paida nahi hoga kyoki un dono integer ke pas already kai facter honge Aur jis integer se divide denge vah bhi us divident me ho sakta hai Samjhe 😅

You are a brilliant TEACHER.

What an explanation sir ji, maza aa gaya👌

Sir what device do you use for writing? If pc then you are a legend

[@ClearExplain]

Thanks, sir you are awesome 🔥🔥😘😘

Thank you sir I am waiting for the video and l understand it ver easily

[@alone7218]

sir very easy after i watch this video thank you so much sir

[@baidyanathmanjhi3687]

Yes sir this vedio is really helpful and thanks for making this vedio

[@alokitkumar]

Thank you sir Ur teaching is beautiful.

[@bhagyalaxminesri9835]

Sir bohot helpful video hain sir

[@neeldutta7]

Hello sir , I have a doubt that ...... • At last we have proved that P and Q have a common factor of 2 . •Means we can write (P as 2m and Q as 2q). •So sir my doubt is that here , we can actually reduce (p/q) to the simplest form of fraction by cancelling 2 from both numerator and denominator. Such as for eg :- We can write (10/20) as (2×5 / 2×10) and can cancel 2 from both numerator and denominator to reduce it to the simplest form to make it coprime. ?? I have watched many videos related to this but have not understood it yet... I will be really thankful to u if u can kindly clear my doubt.

[@sumitparmar6166]

Starting main hi bata diya tha ki dono 'p' and 'q' prime hain means Dono ka 1 hi factor hain

[@sumitparmar6166]

Isliye agar 2 factor aa raha aur vo aur reduce ho rahe hain iska matlab contradiction hua

[@parshantranga1696]

@@sumitparmar6166 agar prime na ho to bhi to rational number hi hone 25/5 is rational even if 25 is not prime

Sir, mujhe ye topic school walo or tuition walo ne yad karne ke liye kaha tha Lekin apne ise samjhaya hain , thank you sir😊

Video is helpful for me sir thanx

[@learning852]

Best explanation about root 2 is irrational no..

[@Learner_Pragya]

Thank you sir 😇👍👍👍👍👍👍👍👍😇😇😃

[@funnify3425]

Sir aap bohot dheri bolti hai Lekin pura samagh mai agaya. Jai hind

[@roopashanthkumar9779]

Thanks a lot sir

[@Samyak-45]

Sir ham√4 ko rational number he ye contradiction method se proof kar sakte hai kya

[@MvpUc0001]

nhi shayad

[@MvpUc0001]

kyuki , under root 4 gives us 2 and we can write 2 in the form of p/q i.e 2/1 . this proove hat root 4 is rational number .

U r the great sir 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻

Thank you sir ye mujhe samajh m aa he nhi raha tha

Thank you ❤

[@anupampandey4127]

Sir! √3 hoga to even kaise krege 2k???????????

[@Snow-w7o]

Tab 2k nhi 3k hoga

[@terobaj903]

​@@Snow-w7otab vi nahi hoga .hoga to kaisa hoga?

[@kashakagrawal1099]

Thank you sir 🌷

[@mrutyujayabaidya8458]

q²=2k² kaise hogaya 4k² Kahan udd Gaya ?

[@anupampandey4127]

Koi bhi even 2k ke form me aata hai aur odd 2k+1 ke form me aata hai😁🙌gyan de rha hu😎
