Ta thấy : 76 . 1000 = 7600
=> 76 . 999 = 76 . ( 100 - 1 ) = 76 . 100 - 76 = 76000 - 76 = 75924
76.1000=76000
Vậy : 76(1000-1)=76.1000-76=75924
76 x 999
= 76 x ( 1000 - 1 )
= 76 x 1000 - 76
= 76000 - 76
= 75924
76 x 999
= 76 x ( 1000 - 1 )
= 76 x 1000 - 76
= 76000 - 76
= 75924
76 . 999
= 76 . ( 1000 - 1 )
= 76 . 1000 - 76
= 76 000 - 76
= 75 924
Học giỏi !
76.999 = 76.(1000-1) = 76.1000 - 76 = 76000 - 75 - 1 = 75925-1 = 75924
\(76.999\)
\(= 76 . (1000 - 1)\)
\(= 76 . 1000 - 76\)
\(= 76000 - 76 \)
\(= 75924\)
HỌC TỐT NHA!!
