hey the answer is...
eg. 5832 find the cuberoot by estimation method.
5 is less than 2 cube so tens digit in the cube root is 1
832 is less than 9 cube so the units digit in the cube root is 8.
hope it helps uu dear. ....

Heya
here's your answer....
Consider the number 19683.
Split the number from the right into group of three digit numbers.
The unit digit of 683 is 3. Hence the unit digit of required cube root must be 7.
We have to estimate the cube root of 19.
Take unit digit of the smallest number.
or......
for example we have 97336
the first three numbers on the right are 336
as the number ends with 6 the square root is also ends with 6
so we have the 97 and the closest perfect cube lesser than 97 is 43(64)
the answer is 64
they are all with examples n will help you 2 solve easily.....
hope it helps buddy....!!
