If we find the cuberoot of 200201625 by Swami Ramkrishna tirth method, we get three answers 525,565 and 585. The digital sum(Bijank) of all these answers is 9 which matches the Bijank of 200201625. Please clarify.

Answer is 585 and to correct you, the digital sum of 565^3 is not 9
thank u so mch fr ds video.😊
Amazing man helped em
Tq for this vedio
please tell these cube root value of 1520875, 1953125, 3048625 those numbers ended with 5 , whenever i used the digital sum process also i did get more number of possibilities for finding 2 nd digit .. what i can do ? for solving that .. if it is 9 digit cube roots value ok for just assuming . but in 12 digit cube there are so many possibilities for finding it....... please link any video for exact properly finding cube roots for all .commonly .......

Why is it a "nice trick"? It is useless in the real world, because it requires that the number you are finding the cube root of be a perfect cube, and that you know it is a perfect cube. Here is a real situation: You are doing a calc and you find you need to find the cube root of 34567.98 to seven digits. Notice that this "trick" could not be used to help you in any way. It is useless, except as a very childish party trick.

@@nikoladjuric9904 Did you do it in these 2 years? The funny thing is, i find many vids teaching the "long division method for cube roots", but every one of them figures it out to about the 3rd digit, and then surrenders, pointing out that "the method becomes prohibitively , long, cumbersome, and impractical" It is not those things -- they just never took the time to figure out how to make it practical I can find the root of any number to the 7th digit in 10 minutes entirely on a card of 4 x 6 inches. Or to 10 digits in less than 20 min, on 2/3rds of a standard sheet. No erasing, no tiny writing, and no calculator assistance. Again, it would be interesting to know. (You should have figured it out by now) I have never met anyone on utube who has figured it out. Not one vid. In my process, i never need to multiply any number by any number other than 2, 3, 4, 6, 8, 10, 12, 14, 16, or 18. I never square any number larger than 9. (Besides that, it is only a whole bunch of addition subtraction, and a bit of mental division). And, for example, for the 7 digit problem, there is never a number more that 8 digits long appearing in the bottom part of the long division configuration, or on the worksheet either. These are MAJOR hints as to what i do. What is it that i do?

Sorry, the number is not just any random nine digit number. It is an EXTREMELY RARE nine digit number, of which there are only 1000 in 1,000,000,000. 1 in a million. Whats more, he knew BEFOREHAND that it was one of these rare numbers. As such there is absolutely no utility in this talent. None. It cannot help in any way to find the cube root of a number which is not one of those rare numbers. Lol, you apparently do not realize that you can teach yourself to find the cube root of ANY number to 8 digit accuracy in less than 10 minutes.
At the outset you say we'll find the cube root in 20 seconds. Two seconds later it becomes fractions of seconds. And then divide into pairs of 3. For Go'd sake a pair is TWO. It should be groups of three. And a billion has 10 digits not nine!

Sir,I think in not well in fundamental mathematics because your video is not in a correct way of teaching ok please learner basics of mathematics then after teach others, thanking you sir:-CHVSN as a INDIAN mathematician but till I am a learner of fundamental mathematics.
Not good
The method is useless. In doing calculations in your math life, you are never going to magically encounter a perfect cube, that you KNOW is a perfect cube. Totally worthless, and a waste of time. Simply learn how to find the cue root of ANY number to any accuracy desired.
