I still remember how to extract a square root without a computer but could somebody remind me the technique to find a cubic root just with the pencil and paper?

Thanks, now it is coming back!Dick said:I'm actually old enough to remember this. It's been somewhat wisely forgotten. http://www.nist.gov/dads/HTML/cubeRoot.html. You may wish to also check out the Isaac Asimov story, "The Feeling of Power". Kind of haunting, these days.
To find the cubic root of a number using the pencil and paper technique, you will need to follow these steps:
Yes, the pencil and paper technique for finding cubic roots is accurate if you follow the steps correctly. However, it may not be as precise as using a calculator or a computer, so there may be a small margin of error.
Yes, the pencil and paper technique can be used for any number to find its cubic root. However, for larger numbers, it may be more time-consuming and difficult to perform the calculations by hand.
The pencil and paper technique for finding cubic roots is based on the concept of successive approximation. It involves repeatedly finding the largest number whose cube is less than or equal to each group of digits in the original number and subtracting its cube from the group of digits. This process is repeated until the end of the number is reached, giving the cubic root as the final answer.
Yes, there are other methods for finding cubic roots such as using a calculator or a computer program, or using the long division method. However, the pencil and paper technique is a simple and convenient method that can be performed without any external tools or devices.
