Finding the Middle # can be dauntling,thank you for you ....the ingenious and strikingly effective way of finding the middle digit for total solution.. thank.... Shukria.....
@Pritam Mishra, On ur observation for 2nd example, The ten's place digit can be 7 instead of 2. Great observations! *Please find the reply.* But you see when we subtract 512 from 552 the result is 040, so when we equate for ten's digit of cube root, we need to equate 3* (8)^2*x=04 192x=04 2x=04 x=2 So ten's place digit of the cube root is 2, can't be 7.
I liked the explation,u explained in a very easy way. Thanks . But i have two questions 1) if in third gp only no 1 is there Ex 1953125 2) what if third term is less than the the cube of one's digit , v r supposed to subtract cube of one's digit from gp1

3* (8)^2*x=04
192x=04
2x=04
x=2
So ten's place digit of the cube root is 2, can't be 7.

Thanks .
But i have two questions
1) if in third gp only no 1 is there
Ex 1953125
2) what if third term is less than the the cube of one's digit , v r supposed to subtract cube of one's digit from gp1
Sir,please make a video on fractional percentages tricks
Sir , the problem given as exercise ,the normal process calculation leads to negative number fo r identifying middle digit. Please clarify
Thank you sir .....
619 is the right 👍 answer❣️
Even i got the same answer
GREAT
Nice
thank thank u thanku thank u thank u very bery very much 👍👍👍 it really helped me solve the rd sharma major doubt
619 is the answer.
How did u get the middle digit?.ok got it
But i got 319
Sir can you explain root cube of 248858189 and 311665752
First one is 629
and second one is 678
Second question me ...x 7 bhi ho sakta tha.....to aap 2 kaise le liye

@@BNMohapatra1964 thank you sirji
Doubt clearer
619
Those 0.1% people do with calculator
I doubt that
619....
