Practice Questions on "Square and Cube Roots" available at: www.careerride.com/mcq/square-root-and-cube-root-quantitative-aptitude-mcq-questions-17.aspx
If unit number would be 8, For example 45968 then how find out square root cause 1-10 all square doesen't have 8 number in the unit number. and also 2,7,3 the numbers would be on unit then how find out square root?
In ques 12, you make the RHS very complex. We can simply do this👇 90/? = (√64/729)^(-1/3) = (8/27)^(-1/3) =(27/8)^(1/3) = 3/2 i.e. 90/?= 3/2 ?= 60. That's it. It's very simple.
Simply a wonderful way to teach. Me just want to add a point. In the problem of square root you just consider the greater than or less than condition to determine the final answer in case of dual conditions. But didn't touch about the "equal to" condition. For example to find square root of 1296. The no whose last digit of square ends with 6 is 4 & 6. The perfect square which is less than 12 is 9 i.e. square of 3. Now 9+3=12. Here the answer is 36. So please add the condition for being equal and it's result.
I have never calculated a cube root of a large number so fast in my life. It's fascinating how simple techniques can boost your calculations over 9000.
Hello sir this channel doing really very good .... I'm impressed... A very little bit simplification going wrong, in question number 8 the product of two numbers is 108 Mistake is in 225-9=216 mentioned as 116. This is not to show your mistake it's just how I follow your class Thanking you...

Sir your video's will be viewed at least a billion sir in recent days you're really great to having that much great teachers sir we all grateful to you sir wish you good days
Hellow sir you said don't multiple 37×37 to get the value of square . But why you multiple 34×40 . Just a 0 will reduced and we add lastly , then we have to find the nearest and the reduced value and the the reduced valve as square
In the square root trick part , what if the number is kind of number which doesn't end in 1,4,6,9,5 and what if it's neither lesser nor bigger but equal then which one to choose , for eg square root of 21078
Thank You very much for your content, with its help I cracked IIM Indore. The best thing about your way of teaching is you explain minutely,then comes the tricks.
At time 10.00 in video if sum of number and it's square is equal to the remaining number in given number then at that time what we do,???Please clarify the doubt. For example take square root of 289
If unit number would be 8, For example 45968 then how find out square root cause 1-10 all square doesen't have 8 number in the unit number. and also 2,7,3 the numbers would be on unit then how find out square root?
Does this rule apply for all numbers or there are few exceptions for this. We actually loved ur trick it's easy to remember and do all coz of the way u explained it is best but please clarify our doubts
Sir, how about this (37)^2 = 1st take square root of 7 = 49 and then 3 = 9 and multiple of 3*7 and then multily with square root i.e 2 , 3*7*2 = 42 so 9 42 49 = 1369 ans.
We have to rationalise the given prblm.so so we have to multiply by and devided by the same value with opposite sign .then apply (a+b) (a-b) formula,then you get a^2-b^2 .so roots get cancelled .in the upper portion you have 5+3(1.41.) devide by 7.then you get the answer 1.320
Guys I say this technique is really big...it's not a short trick....I find many shortcuts in another Channel..it's very easy...Im just sharing becuz I found another method easy it's not tough but this contains more steps

Trick 3 ??????????
If unit number would be 8, For example 45968 then how find out square root cause 1-10 all square doesen't have 8 number in the unit number. and also 2,7,3 the numbers would be on unit then how find out square root?
In ques 12, you make the RHS very complex. We can simply do this👇
90/? = (√64/729)^(-1/3)
= (8/27)^(-1/3)
=(27/8)^(1/3)
= 3/2
i.e. 90/?= 3/2
?= 60.
That's it. It's very simple.
Yes its so simple I am also thinking the same
Simply (√64/729)^-1/3 = ( √729/64)^1/3 flip the numbers to remove negative sign then √9/4 = 3÷2
Simply a wonderful way to teach.

Chill re
Exactly!!
In Q.8 225-9=216
2AB=216
So AB =108
Yes same
The square root and cube root tricks are really helpful.Thank you so much

Your teaching Excellent sir 👍
you are really intelligent sir 👍👍👍👍👍
Hellow sir you said don't multiple 37×37 to get the value of square . But why you multiple 34×40 . Just a 0 will reduced and we add lastly , then we have to find the nearest and the reduced value and the the reduced valve as square
Your video very helpful sirr
thank you sir. its good

If unit number would be 8, For example 45968 then how find out square root cause 1-10 all square doesen't have 8 number in the unit number. and also 2,7,3 the numbers would be on unit then how find out square root?
3 digits and 5 digits numbers we can find the square root then what about if the numbers has 4 digit ? How to find square root??
You can directly find out by using (a+b)^2 or (a-b)^2.
Good,but questions taken was very easy
Sir, plzzzzz post set theory questios and tricks
Does this rule apply for all numbers or there are few exceptions for this. We actually loved ur trick it's easy to remember and do all coz of the way u explained it is best but please clarify our doubts
squaring with multiplication approx takes 20 second
Thank you 💗
Q. No. 8 answer is 108 correct one
Super
Sir, how about this (37)^2 = 1st take square root of 7 = 49 and then 3 = 9 and multiple of 3*7 and then multily with square root i.e 2 , 3*7*2 = 42 so 9 42 49 = 1369 ans.
25:59 sir , why we need to get the difference as 1 ?
What should be the difference, if it is cube root or 4th root

Dear sir could u please help us to find square root for more than 5 digits number,
Please update your class you are teaching a long calculation
Can u plz explain q 7 in detail , why can't we square the whole term? I m getting 0.877 as ans
We have to rationalise the given prblm.so so we have to multiply by and devided by the same value with opposite sign .then apply (a+b) (a-b) formula,then you get a^2-b^2 .so roots get cancelled .in the upper portion you have 5+3(1.41.) devide by 7.then you get the answer 1.320
thankyou sir!!!!
really helpful

Sir in 8th question..lhs=216.(since 225-9=216)
In ques 8 ..the correct answer is 108 as 225-9 is 216 and then divided by 2 is 108
How to find square root of 1471369 using these tricks because it's a long term and plz suggest how to solve it.
Square root trick does not apply for number 2401 . Please sir let us know why is it so
at Q-11 how did you turn 2 square root 3 = under root 12.
can't understand that concept.
Square Root 4 =2
In ques 2 * square root 3 ==2 goes inside the square root and it becomes 4 =square root (4*3) = square root 12
In que 12, can we flip if there is (-1/3) in power just like (-1/2).
Ya of course. That's a general rule
Could u find the square of 1734489 bcuzz u have solved upto 5 digits no. ND m finding it difficult to solve
1317
8th question answer is 108....you had wrongly calculated the answer as 58
Appreciative
Sir can u please find the square root of 24696 by using trick 3
160 answer
Sir in this there is one question in which you had done a mistake in which you have taken 116 instead of 216 for true answer.
But instead doing that v can do 37*37 right
Question 8 -ans is wrong
225- 2AB =9
2AB =216
AB =108
answer is 108
sir ,in question no 4 why should we only consider pair with difference 1 ??
11:56 anyone please help me , can we able to find square root of 6 digit or 7 digit number using this method
