.giúp mk tính từg bước

Answer 1

\(2345-1000:\left[19-2\times\left(21-18\right)^2\right]\)

\(=2345-1000:\left[19-2\times3^2\right]\)

\(=2345-1000:\left[19-18\right]\)

\(=2345-1000\)

\(=1345\)

Answer 2

2345-1000:[19-2(21-18)²]

= 2345-1000:(19-2.3²)

= 2345-1000:(19-2.9)

= 2345-1000:(19-18)

= 2345-1000:1

= 2345 - 1000

= 1345

Answer 3

2345 - 1000 : [ 19 - 2 (21 -18 )²

= 2345 - 1000 : [ 19 - 2 . 9]

= 2345 - 1000 : [ 19 - 18 ]

= 2345 - 1000 : 1

= 2345 - 1000

= 1345
