k mình nha
35 . 12 + 65 . 13
= 35 . 12 + 65 . ( 12 + 1 )
= 35 . 12 + 65 . 12 + 65 . 1
= 35 . 12 + 65 . 12 + 65
= 12 ( 65 + 35 ) + 65
= 12 . 100 + 65
= 1200 + 65
= 1265
minh nham:

Chúc bạn hok tốt
35×12+65×13
=35×12+65×12+65
=(35+65)×12+65
=100×12+65
=1200+65
=1265
Kết quả bằng 1265 nha các bạn,chúc các bạn học tốt
35.12+65.13=35.12+65.12+65
=12.(35+65)+65
=12.100+65

\(35.12+65.13=35.12+65.12+65\)
\(=12.\left(35+65\right)+65\)
\(=12.100+65\)
\(=1200+65=1265\)
Học tốt !
35.12 + 65.13
= 420 + 845
