## Trick 1.

### Cube root for 2406104:

Number         Split as
2406104       2406 | 104
Split the number keeping the last 3 digit aside
13^{ 3 }  (2197) < 2406 < 14^{ 3 }  (2744)
Choose the smaller number (13) as the 1st Part
 If the cube ends in 1 2 3 4 5 6 7 8 9 0 The no. would end in 1 8 7 4 5 6 3 2 9 0
13     |       4
Ans. 134
