11 . 25 + 95 . 11 + 89 . 51 + 69 . 89
= (25 + 95) .11 + (51 + 69) . 89
= 120 . 11 + 120 . 89
= 120 . (11 + 89)
= 120. 100
= 12000
\(11.25+95.11+89+51+69.89\)
\(=11\left(25+95\right)+\left(89+51\right)+6141\)
\(=11.120+140+6141\)
\(=1320+6281\)
\(=7601\)
Ung ho nha

11.25 + 95.11 + 89 + 51 + 69.89
= 11( 25 + 95 ) + ( 89 + 51 ) + 6141
= 11.120 + 140 + 6141
= 1320 + 6281
= 7601
11.25 + 95.11 + 89 + 51 + 6.89
= ( 25 + 95 ) . 11 + ( 51 + 69 ) . 89
= 120.11 + 120.89
= 120 . ( 11 + 89 )
= 120. 100
= 12000
Bài lúc nãy mình làm sai !
