Odd numbers main Zero aa zai matlab kya hain.... Kehna kya sahta hain . video time 16.43 minutes.

[@shreyasingh04.05]

​@@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

[@shreyasingh04.05]

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...?

[@gourovdey1319]

did you find the answer?

[@nisthur]

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

[@khanarun]

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
