Suddenly it occurred to me that without scientific calculator, it is difficult to achieve; as, CA IPCC students are allowed to use only the standard calculator in examination. I. then decided to search a technique for quick calculation of cube root with a standard calculator or even without any calculator.
As expected, there were numerous resources on this subject, but many were giving complicated techniques of the same. I found three links which explained the concept nicely and in a simple manner for every CA IPCC student; whether with or without mathematics background.
- Check this link from the blog page of www.1729.com to know step by step technique of finding cube root of 3 digit, 6 digit or 9 digit numbers.
- Check this link from wikipedia to know the steps of calculating cube root by a standard calculator.
- Last but not the least, check this video to know a simple technique of quick calculation of cube root of a perfect cube not exceeding 6 digits.( remember the technique in the video is not applicable for a number which is not a perfect cube or which contains more than 6 digits)
All the Best for your CA IPCC studies.
