Answer 1

Step-by-step explanation:

For calculating the cube root of 5832, this number has to be separated in two group, i.e. 3 and 832.

considering the group 832:

832 ends with 2 and we know that if digit 2 is at the end of any perfect cube number, then its cube root will have 8 at its unit place only. Therefore, the digits at the units place of the required cube root is taken as 8.

Now consider the other group 3:

We know that the 13=1 and 23=8
