Sir, i had apply your digit sum trick on 235 to identify it is a perfect square number or not. Its digit sum is 1. So i take it as a perfect square no. But when i checked it. It turned out be a non perfect square number. Please tell my mistake sir.😕😕😦
Sir as per ur 3rd rule as you said if 6 is on the ones digit than if any odd number is there on the tens digit it will be a perfect square as in 876 where 6 is on the ones digit and 7 on the tens digit and which is actually not a perfect square
If last 2 digit no. R 25 hundreds place must be either one of the digits 0,2,6 but all r having but if u apply division method finding square root . the First 2 digit no. r 36 is perfect square it is divisible by 6 but still process must b done but not divide therest of no. r the explanation takes more time if you think it is solved in seconds
Harsh Beriwal My dear jese 10 ka square 100 hota h means 100 m 2 zero h it means pair m h 150 ka sqaure 22500 hota h means 22500 m 2 zero it means pair m h Aise he agr 1100 ka square kre toh 1210000 hoga or isme bhi 4 zero g it means 2 pair h Toh mene yeh bola tha 0 pair m hoga hmesha jo bhi no. Perfect square hoga Samjh aaya ??

sir you told if last 2 digit comes in 1 to 24 square in any no. will be perfectly square no. . but in your video timing 12:22 no is 680621 is not a perfect square
Even if a number satisfies all the above conditions, it is not necessarily a perfect square. No foolproof shortcut trick is available to determine whether a number is perfect square or not.
The only 3-digit perfect square number ending with 89 is 289 . All other 3-digit numbers ending with 89 are not perfect square. Hence 189 is not a perfect square.
Prime factorize 3456. 3456=9*384 = 9*6*64 = 3*3*3*2*8*8 = (3^3)*(2^7) Here 3 and 2 are prime factors. Exponent of both 3 and 2 are ODD number. A perfect square always contains EVEN number of all its prime factors. If any one of the prime factors has ODD number of exponent, then the given number is not a perfect square. Hence 3456 is not a perfect square.
@@SwatiSharma-lp6vh it is not mentioned that any number which satisfies all the above conditions is a perfect sq. but the numbers which really are perfect sq will definitely satisfy all the above conditions.... vice versa is not necessarily true. for eg, a quadrilateral which has all sides equal may not necessarily be square, but the reverse is true that square has all the four sides equal! But the former can be a rhombus which also has equal sides... Hope it helps!!
@@aayushniket2446 means there is no any method to find correct answer of given choices!!! We have to remember some other points to mark the correct ans.... ...like prime No's. We have no any perfect method which can tell us ..a given no. Is prime or not....

sir according to you tactic add all the units digit so in 1381 if we add we get 13 furtherly adding 13 we get 4 so this number should be a perfect square as per your trick. But still the number is not a perfect square.

Please Reply if the number will not satisfy Any of these law.will that number be a perfect square or not.. Sir please rply
Even if a number satisfies all the above conditions, it is not necessarily a perfect square. No foolproof shortcut trick is available to determine whether a number is perfect square or not.
Hello sir,
Your trick is not applicable for 189. Why please explain
The only 3-digit perfect square number ending with 89 is 289 . All other 3-digit numbers ending with 89 are not perfect square. Hence 189 is not a perfect square.
Great explanation

Sir please tell 3456 is perfect square Or non perfect square And how with explanation plzzz .....
Prime factorize 3456.
3456=9*384 = 9*6*64 = 3*3*3*2*8*8 = (3^3)*(2^7)
Here 3 and 2 are prime factors. Exponent of both 3 and 2 are ODD number.
A perfect square always contains EVEN number of all its prime factors.
If any one of the prime factors has ODD number of exponent, then the given number is not a perfect square.
Hence 3456 is not a perfect square.
396 is one of the numbers which satisfies all the conditions but still not a perfect number.
Yes dear as 876 also doesn't follow the same
