Question

15.{32:[6-5+5.(9:3) ] }

Answer 1

15.{32:[6-5+5.(9:3)]}

= 15.{32:[1+5.3]}

= 15.{32:16}

= 15.2

= 30

Answer 2

15.{32:[6-5+5.(9:3)]}

= 15.{32:[1+5.3]}

= 15.{32:[1+15]}

=15.{32:16}

= 15.2=30

Answer 3

Ta có \(15.\left\{32:\left[6-5+5.\left(9:3\right)\right]\right\}\)

\(=15.\left\{32:\left[6-5+5.3\right]\right\}\)

\(=15.\left\{32:16\right\}\)

\(=15.2\)

\(=30\)

Answer 4

15 . { 32 : [ 6 - 5 + 5 . ( 9 : 3 ) ] }  

= 15 . { 32 : [ 6 - 5 + 5 . 3 ] }

= 15 . { 32 : [ 6 - 5 + 15 ] }

= 15 . { 32 : [ 1 + 15 ] }

= 15 . { 32 : 16 }

= 15 . 2 

= 30
