Question

find the cube root of 52983 by the method of estimation​

Answer 1

Answer:

Ans- 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 1 ^3=1 and 2^3=8

Also, 1<5<8

So, 1 will be taken at the tens place. So, the required cube root of 5832 is 18.

3√5832 =18
