Question

Answer 1

\(=200+3\left(109-9\right)=200+3\cdot100=500\)

Answer 2

200 + 3 ( 109 −9 )

= 200 + 3 ⋅ 100

= 500

Answer 3

200+3.[109-\(3^4\):\(3^2\)]

     =200+3.100

           =200+300 

                =500

Answer 4

\(200 + 3 . [109 - 3^4 : 3^2]\)

\(200 + 3 . [109 - 3^2]\)

\(200 + 3 . [109 - 9]\)

\(200 + 3 . 100\)

\(= 200 + 300\)

\(= 500\)
