Trick 3 ??????????

[@vishnurandive1081]

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?

[@Desi_vyanjan]

Anyone 2024😂

[@divyadoddagoudar5153]

225-9=216 but it is written 116 so the correct ans is108

[@letsbgm2546]

its human error guys ..so dont take it serious .. everyone easily got ths but the way u teach sir fabulous ..👍👍👍thanks

[@dheerajpoonia2175]

Chill re

[@afirifad8160]

Exactly!!

[@prateekgupta8861]

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.

[@subbusubbu7726]

Yes its so simple I am also thinking the same

[@asiya504]

Simply (√64/729)^-1/3 = ( √729/64)^1/3 flip the numbers to remove negative sign then √9/4 = 3÷2

[@apurvasakure1364]

In Q.8 225-9=216 2AB=216 So AB =108

[@iote47_amolkadam28]

Yes same

[@PaAGadirajuSanjayVarma]

The square root and cube root tricks are really helpful.Thank you so much

[@pritamsaha86]

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.

[@chirukhush]

Question no.8 225-9 = 216 216/2 = 108

[@sangeedarshi7423]

8th question answer is 108....you had wrongly calculated the answer as 58

[@showkethaneef3998]

Your way of teaching is excellent

[@durugeshjaana7670]

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...

Question 8 -ans is wrong 225- 2AB =9 2AB =216 AB =108 answer is 108

[@vishnurandive1081]

at Q-11 how did you turn 2 square root 3 = under root 12. can't understand that concept.

[@shankarp9029]

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

Q.8) 225-9=216 but it is written 116 and that is wrong, So the correct answer is 108.

[@ashutoshsahoo1870]

You can directly find out by using (a+b)^2 or (a-b)^2.

[@koushickshankar]

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

[@tapishkour3627]

Can u plz explain q 7 in detail , why can't we square the whole term? I m getting 0.877 as ans

[@narayanaswamg9338]

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

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.

[@aramtabassum9233]

In ques 8 ..the correct answer is 108 as 225-9 is 216 and then divided by 2 is 108

[@vishalghuge8520]

Q. No. 8 answer is 108 correct one

[@mathewanil465]

question number 8 - Product AB is 108 , 225-2ab=9, therefore 2ab=216, so ab = 216/2 = 108.

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

[@saurabhpatel4858]

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.

[@ashoksaipudi6999]

Sir the trick you told for cube roots is failed for the values whose cube ending value for that cube number Ex: 323149 323 nearest cube is 6 and last value is 9 So the answer is 69 but in calculator it's showing another number could you clarify my doubt
