14,58 . 460 + 7,29 . 540 . 2
= 14,58 . 460 + 14,58 . 540
= 14,58 . ( 460 + 540 )
= 14,58 . 1000
= 14580
A = 14,58 . 460 + (7,29. 2 ) . 540
= 14,58 . 460 + 14,58 . 540
= 14,58 . (460+540)
= 14,58 . 1000 = 14580
Tk mk nha
A = 14,58 . 460 + 7,29 . 540 . 2
= 14,58 . 460 + (7,29.2) . 540
= (460 + 540).14,58
= 1000.14,58
= 14580
Bài làm :
A = 14,58 x 460 + 7,29 x 540 x 2
A =6706,8 + 7873,2
A =14580
Vậy A = 14580
