@@Smiley6_12 we have to choose a square less than the number, so it's 16 . Which is 4 . Now to choose greater or smaller number we multiply the number with the next number , like in this case the number is 4 and the next Is 5. So , 4*5 = 20 ; which is greater than 18 . So we choose the smaller number
@@pmlakshmimurugan9284 no, although square root of 7 is near to 47 but we have to take lesser than the number 47 that is 36 , therefore 69 would be the correct answer :)
This rule fails when no. is not a perfect square and by this method we will be not be able to find square roots in decimals. E.g. √4361 = 66.0378 not 69 💀💀
I loved it ma'am thankyou so much for this helpful trick ❤😊 Ans - 69,43🎉 I do practice for it also and it clear all doubts of mine once again Dhanyawad 🙃
Can any please tell me how square root of 1849 comes 43 .... As 9 can be last digit of square of 7 or 3 and 16 is closest square of 18 now of we multiply 4 with 5 then 20 comes that is bigger than 18 so we put 7 na instead of 3??
No no no, you just have a mis-conception. The product of 4 and 5 will be 20 and now the first 2 digits of the number i.e 18 is smaller than 20 hence we chose 3 instead of 7. Thus the under root is 43. But don't try this trick in a non perfect square root number , it will give a wrong answer. So firstly be sure that the number you want to take under root is already a perfect square. I have tested it.
If N = (√(√5) +2+ √(√5) -2)/(√(√5) +1)-√(3-2√2) Find the value of N Options : a) 1 b) 2√2 c) √5/2 The answer is 1 but I want the explanation. It is from class 9 maths Olympiad book
Yes because, 1.First take last two digits that means 89 3/7 has the squares ending with 9... 2.Take the remaining number that is 2 the least square to that is 1 , then the first digit is 1 so multiply by 2(because it is the next number as mam told)... The answer is 2. 3>2... 3 is greater than 2. So take the greatest number from the first step we have done that is 7 So the Answer is...........17 17^2=289 💯💯
Thank you ma'am for this trick 😃
The square root of 4761 is 69 and of 1849 is 43
Thanks a lot mam thats why byjus is awesome and i got really best trick ❤❤❤❤😊
Very good trick thanku so much
Thanks ma'am for this amazing trick
TYSM MAM
√4761 = 69
√1849 = 43
It is very easy now.
thank you for the trick ma'am.
Thanks for this amazing trick.

Thankyou mam such a easy trick
Tomorrow is my exam it helps me in finding the root 🎉❤
Wow
Thanks a lot

Thanks ma'am
Thanks man
Mam, please let me know if any conditions are there for this method.

thank you mam
Thank you ma'am for this trick 😊 the square root of 4761 is 69 and 1849 is 43.❤🎉❤🎉😊😊
I have a doubt , why it is not 47? Cuz we got 3,7 or the last digit and as 18 is greater than 16 we have to choose 7 na ? Can u explain plz..

Naer 47 number there is a square root of 7 that means the answer would be 79 ? Am I right

Cool Trick
If N = (√(√5) +2+ √(√5) -2)/(√(√5) +1)-√(3-2√2) Find the value of N
Options : a) 1 b) 2√2 c) √5/2
The answer is 1 but I want the explanation. It is from class 9 maths Olympiad book
THANKYOU!!❤️
What if there is zero??
Is it valid for 3 digit number too??
Like 289
Yes because,
1.First take last two digits that means 89
3/7 has the squares ending with 9...
2.Take the remaining number that is 2
the least square to that is 1 ,
then the first digit is 1
so multiply by 2(because it is the next number as mam told)...
The answer is 2.
3>2... 3 is greater than 2.
So take the greatest number from the first step we have done that is 7
So the Answer is...........17
17^2=289
💯💯
