The identity used will be - a^3+b^3+3ab(a+b)
103= 100+3
Therefore, (103)^3 = (100+3)^3
Where a=100 b=3
According to the identity,
(100)^3+(3)^3+3(100)(3)(100+3)
100000+9+(900)(103)
100000+9+927
100000+936

103= 100+3
Therefore, (103)^3 = (100+3)^3
Where a=100 b=3
According to the identity,
(100)^3+(3)^3+3(100)(3)(100+3)
100000+9+(900)(103)
100000+9+927
100000+936
