(103)³ = (100 + 3)³

(a + b)³ = a³ + b³ + 3 x a² × b + 3 x a x b³
           = 100³ + 3 ³ + 3 ×100² × 3 + 3 × 100 × 3²
             = 100000 + 27 + 90000 + 2700
                  = 1092727

(103)³=(100+3)³

(a + b)³ =a3 + b3 + 3ab(a + b) [use this identity to solve it}
          
= 100³ + 3 ³ + 3 ×100 × 3 ( 3 + 100 )
            
 = 100000 + 27 + 900 x 300

     =1000027+270000
=1270027
