Need to remember 1 to 20 cube and this so easy for any one.
Example 1:
3√3869893 = ?

Answer :
Step 1: Last digit of cube number from right side is 3 that we consider 343 = 73 we put down 7. Then
Step 2: Take the number whose cube is nearest to 3869.That is 3869 is nearest to 153 and 163 we take small one cube digit that is 15.
