Question

2345-1000:[19-2(21-18)²]

Answer 1

2345-1000:[19-2(21-18)²]

= 2345 - 1000 : [19-2x3² ]

=2345-1000 : [19 - 2x9]

= 2345 - 1000 : [19 - 18]

= 2345 - 1000 : 1

= 2345 -1000

= 1345

Answer 2

\(2345-1000\div\text{ }\left[19-2\left(21-18\right)^2\right]\)

\(=2345-1000\div\left(19-2.3^2\right)\)

\(=2345-1000\div\left(19-2.9\right)\)

\(=2345-1000\div\left(19-18\right)\)

\(=2345-1000\div1\)

\(=2345-1000\)

\(=1345\)

Answer 3

2345 - 1000 : [ 19 - 2 (21 - 18)² ]

=2345 - 1000 : ( 19 - 2 x 3² )

=2345 - 1000 : ( 19 - 2 x 9 )

=2345 - 1000 : ( 19 - 18 )

=2345 - 1000 : 1

=2345 - 1000

=1345

Answer 4

2345 - 1000 : [ 19 - 2 (21 - 18)² ]

=2345 - 1000 : ( 19 - 2 x 3² )

=2345 - 1000 : ( 19 - 2 x 9 )

=2345 - 1000 : ( 19 - 18 )

=2345 - 1000 : 1

=2345 - 1000

=1345
