Odd numbers main Zero aa zai matlab kya hain.... Kehna kya sahta hain . video time 16.43 minutes.
@@bishalgogoi8428square from 1 to 9 there is no zero in unit place and sq of any zero is even numbers of zeros
Ex- 10²=100 , 20²=400 , 120²=14400
Conclusion- only squares of zeros(any number containing zero as its unit digit) have zeros in the last digit and also it has to be even number of zeros

Best math teacher in my life
285616 is a number which is non perfect square as per calculator but none of the non perfect tricks applied on it
-Unit digit is 6(not 2,3,7,8)
-2+8+5+6+1+6=28=1(not 2,3,5,6,8)
-The last two digit is square of 4=16
-Last digit 6 with a odd second last digit
So these are the tricks for multiple choice questions they don't have accuracy. And if multiple choice questions have 'none of these' as an option..?? The only option we have if we need accuracy is the division method...?
did you find the answer?
17:07
1) 690828 non perfect we all know
3) 786920 non perfect caz single zero .
but
2)790321 is a perfect square
and also
4) 597226 is a perfect square caz after addition
5+9+7+2+2+6
= 31
=3+1
=4
and we all know that if last digit is 4 then it's a perfect square
Same case, for number 316 these tricks for non perfect square doesn't align.
Amazing sir mera clear ho gaiya 😍
Really awesome....cleared my biggest doubt 👍
Hi sir mujhe bhi add karenge
Sir so... thanks now i can do it in seconds..... Thanks so much.

Your trick was amazing but there is much confusion
A Perfect square sir
Yes sir
Sm sir
Last question ka (C) is the correct answer.🤗
Sir bahut acha pdhaya🙏
sir the concept was amazing but digital wass to easy can we solve evrey ques. by digital......m little confused can you reply.....plezzz i like your concepts.....
For faster calculation of digital sum, always neglect digit 9 or any combination with sum as nine.
2. Start collapsing the sum as soon as it exceeds 10, IE if one gets 14 or 17 etc, make it 5&8 respectively and continue.
One need not do addition of any number greater 9.
It's time consuming.. Do subtract by 9 then add
Don't make things more complicated bro
Really nice work by wi fi study group.🙏🙏 Thank you

Sir ji
wow very nice class😘
Good video 🙏🙏🙏👍,
Sir, kindly reply, how applying ur noperfect funda, we can show 4576 is a non perfect square.
1. Last digit 6. 2. There is odd no.7 before 6 . 3. Digital sum is 4. 76 is the last two digit of 24^2.All 4 indicate that it is a perfect square. But it is not a perfect square why?
Sir ne bola h non perfect square surely keh sakte ho agar koi ek bhi condition mil jaye unki batayi hui n... Bt perfect square surely nai keh sakte h.. Is number m sir ki batayi hui conditions se ye confirm nai ho raha hai ki ye non perfect square h bt that doesn't mean ki ye perfect square hoga... In such type question we have to use division method to check...
Where we use division method
Sir told that we can positvely say which no is non perfect. He has stated some rules. All rules justify 4576 is a non perfect square. But is it so? So we also can't always say which no. Is nonperfect.
