/d

where s=sub-base, d=difference
(i) 103
base=100;
sub-base=[103/100]=1
d=103−(100×1)=3
Cube=1

(103+2(3))/1×3(3

)/3

As base is 100, we'll take two digits 109/27/27
1092727
(ii) 105
base=100; sub-base=[105/100]=1
d=105−100×1=5
Cube=105+2(5)/3(5
2
)/5
3
=115/75/125
=1157625
(iii) 107
base=100; sub-base=[107/100]=1
d=107−(100×1)=7
Cube=107+2(7)/3(7
2
)/7
3
=121/147/343
=1225043.
