Welcome

[@mallikasarmah9088]

Thanq sir for giving us concept about various topics

[@shilpamanjunath757]

Nice explanation sir tq

[@jyotisaikia6448]

Hi Sir, your videos are so good to learn the concepts and It will be so helpful if you provide the solution of 63 and 64 of June 2016, Set A.
Thank you!

[@gauripatil1095]

Very helpful thanku very much

[@durgeshpandey101]

Thanks for clearance. I had also correct these three options sir but in many famous coaching books, answer keys and vedios have wronged the third option giving the arguement that when set is finite, power set has cardinality finite and when set is countable then Power set has cardinality uncountable. So, I was in doubt

[@sunandapatra2774]

Yes sir

[@sunandapatra2774]

Thank you thank you sir so much

[@mdsarijulislam8926]

Gd explanation

[@hafizur12349]

Thank you so much sir

[@positivevibes1219]

Sir cardinality kyu find ki simple set ka poochha hai plz explain sir

[@shalu4839]

Amazing

[@riteshraj5424]

Good explanation sir thanks

[@tripathitripathi4313]

Very nice explain

[@reenarai1927]

Sir N = countable & card(P(N))= c
It means 3rd option should be wrong & baaki overall nice explained by u.

[@mdsarijulislam8926]

Reena Roy 3 option is true for some countable set A

[@amazingpro-]

@@mdsarijulislam8926 but we have contradiction for this , if we take set of natural no.

[@sonalirangra5611]

Its for some A not for all A

[@reenarai1927]

Ok thanku

[@RKMaths1]

Countable set means finite or countably infinite.
For 3 option, give a example which P(A) is countably infinite.....

[@RahulMapariBasicMaths]

No. There is no Set A such that P(A) is countably infinite

[@amarjyotialka6939]

Sir options 3 me confusion hai. Kyoki power set ki cardinality ya to finit hoti hai ya uncountable. Sir please explain.

[@vrushabhawati4967]

Hello sir ... kya aap CSIR ke pure tutions lete ho ... not just important questions ...par pura basic se ...

[@naveendc5595]

Thank you Sir

[@shubhamkumarsingh7490]

Thanks sir

[@samvlogs7378]

Nice #mathophilic

[@khushboomiddha2314]

Thank you sir, confusion answer me thi,kyonki 3rd option ko.galat btaya gya tha according to Walter Rudin.

[@vikassrivastava7979]

BY convention every finite set is countable. take any finite set you can find a injective map from that set into the natural number so by definition it is countable.

[@vikassrivastava7979]

And you can show that there is no set such that power set is countable. I mean you can never find a set whose power set is countable. It is result.

[@mohapatradhabal298]

Sir abstract ka ek doubt hai.. suppose d divides order of G then how to check that there is an element of order d.

[@RahulMapariBasicMaths]

Firstly, It is not always possible that if d divides order of G then it has element of order d.
Eg- kliens four Group has no element of order 4
Actually this is depend on group, if it is cyclic then whatever divisor of order G it has element.
For non abelian it is different. So plz try to read how to analyse structure of group.

[@mdkausarsk8033]

Sir if you take A=phi then P(phi)=phi ,then option A will be correct ? Please give me answer

[@RahulMapariBasicMaths]

No. P(phi)=1

[@saini_writes]

It's not phi it's {phi}

[@shivarenke8082]

Sir thanks for video but sir please make clear video

[@RahulMapariBasicMaths]

Now videos are clear

[@yuvaraj45]
