Question

[Đỗ Minh Anh]

(20 + 8) . {480 - [11 . (64 - 2^{2}) : 2]}

Answer 1

[Ga'l wes]

( 20 + 8 ) . { 480 - [ 11 . ( 64 - 2² ) : 2 ] }

= 28 . { 480 - [ 11 . ( 64 - 4 ) : 2 ] }

= 28 . [ 480 -  ( 11 . 60 : 2 ) ]

= 28 . [ 480 - ( 660 : 2 ) ]

= 28 . ( 480 - 330 )

= 28 . 150

= 4200

Answer 2

[Nguyễn Quang Dũng]

\(=28.\left\{480-\left[11.62:2\right]\right\}\\ =28.\left\{480-\left[11.31\right]\right\}\\ =28.\left\{480-341\right\}\\ =28.139\\ =3892\)
