0For an eg: Find the cube root of 21952?
Answer: Divide the number in two part first two number in one part and other three number in second part.
Then in number 952 take last number is 2 then see in which cube root of 1 to 9 the number 2 come on unit place it cube root of 8 then the unit place of 21952 is 8.
Now take 1st two number 21 and see it lie between which cube root from 1 to 9 then cube root of 2 is 8 and cube root of 3 is 27 then 21 lies between cube root of 2 and 3, 8 < 21 < 28. Then take smaller one is 2 and put it as ten's place of 21952.
So, final answer of cube root of 21952 is 28.
