Answer 1

1600

16

Answer 2

`16xx48+16xx24+16xx28`

`=16xx(48+24+28)`

`=16xx100`

`=1600`

`325-317+426-418`

`=(325-317)+(426-418)`

`=8+8`

`=16`

Answer 3

`16 xx 48+16xx24+16xx28`

`= 16 xx ( 48 + 24 + 28)`

`= 16 xx 100`

` = 1600`

 

`325-317+426-418`

` = (325-317)+(426-418)`

`= 8 + 8`

` = 16`

 

Answer 4

16 x 48 + 16 x 24 + 16 x 28

= 16 x ( 48 + 24 + 28 )

= 16 x 100

=1600

325 - 317 + 426 - 418

= 8 + 8

=16

Answer 5

Tính nhanh

16 x 48 + 16 x 24 + 16 x 28

= 16 x ( 48 + 24 + 28 )

= 16 x ( 76 + 28 )

= 16 x 104

= 1664

325 - 317 + 426 - 418

= ( 325 - 317 ) + ( 426 - 418 )

= 8 + 8

= 16.
