  1. $$ 2006 × (43×10 -2 ×43 ×5) +100 $$ $$ = 2006 × (43 ×10 – 10 ×43) +100 $$ $$ = 2006 × 0 +100 $$ $$ = 0 +100 $$ $$ = 100 $$

  2. Giải đáp:
    100 
    Lời giải và giải thích chi tiết:
    2006 xx ( 43 xx 10 – 2 xx 43 xx 5 ) + 100
    = 2006 xx ( 43 xx 10 – 10 xx 43 ) + 100
    = 2006 xx 0 + 100
    = 0 + 100
    = 100
