- here is the simplest formula to approximate cube root of any number!
it is very complicated to calculate the cube root of a number.
that is because we have to deal with the cube of a number.
but there is a simplest calculation tricks to approximate the cube root.
we can express the accurate approximations as a fraction in just one step.
this video shows the formula to approximate the cube root and explains its principles behind it.

This is an interesting video because it's a deep analysis of cube root. Not sure of the practicality in the 21st century though. It still requires pencil and paper (for me anyway!). Incidentally, in the first example, to two decimal places 4.14583 rounds to 4.15 but the exact value rounds to 4.14. I think anyone able to understand this video should move on to calculus and beyond and let the calculator handle roots. Don't worry, we still meet up with numerical approximation along the path; for example, Newton's Method to approximate the solution of certain differential equations. Best wishes to all for an enjoyable new year 🙂
definitely it couln't be pratical in this age of AI. I had fun when thinking about the principles with paper and pencil. happy and healthy 2025~~
