Answer :-
______________________
★ Method - 1
102³ - 2³
= ( 102 - 2 )³ + 3 × 102 × 2 ( 102 - 2 )
= ( 100 )³ + 612 × 100
= 1000000 + 61200
= 1061200 [ ★ Required answer ]
Note :-
Used identity : a³ - b³ = ( a - b )³ + 3ab ( a - b ) [ • Where , a = 102 and b = 2 ]
★ Method - 2
Simply ,
102³ - 2³
= 1061208 - 8
= 1061200 [ ★ Required answer ]
