How to find the Cube root of large numbers

In this article we are going to learn how to find the cube root of large numbers. Just focus on the below trick you will be able to find the cube root of any number within 1 minute.. We need to learn some basics to solve these questions.




Numbers            Cubes                  Last Digit(units digit of cubes)

 

1                             1                              1
2                             8                              8
3                            27                             7

8                           512                            2
9                           729                            9
10                         1000                          0


Note: The large numbers which has 4,5,6 digits long will have cube roots answer is 2 digits long.
 Ex  :

 In the above example question consist 6 digit number . so that answer will be 2 digit number.


Example :we will solve by using trick.

Ans:

• Take the unit digit of question . I. e 4. and look at above table  as shown below.

• We will take the number from first column i.e 4 and write it in units place of answer.

                          

• Ignore the 3 digits from the right side as shown below.



• Look at the remaining numbers i.e 39 in the question. check the 39 number in cubes column as shown below.

• choose the lower number in corresponding NUMBER Column 27 means 3.

Answer will be
