Question

400 : { 5 . [360 - ( 290 + 2.5^2)]}

Answer 1

`400 : { 5 . [ 360 - ( 290 + 2 . 5^2)]}`

`=400 : { 5 . [ 360 - ( 290 + 2 . 25)]}`

`=400 : { 5 . [ 360 - ( 290 + 50)]}`

`= 400 : { 5 . [ 360 - 340]}`

` = 400 : { 5 . 20}`

` = 400 : 100`

` = 4`

Answer 2

`400 : { 5 . [ 360 - ( 290 + 2 . 5^2)]}`

`=400 : { 5 . [ 360 - ( 290 + 2 . 25)]}`

`=400 : { 5 . [ 360 - ( 290 + 50)]}`

` = 400 : { 5 . 20}`

` = 400 : 100`

` = 4`

Answer 3

\(400:\left\{5\left[360-\left(290+2.5^2\right)\right]\right\}\)

\(=400:\left\{5\left[360-\left(290+2.25\right)\right]\right\}\)

\(=400:\left\{5\left[360-\left(290+50\right)\right]\right\}\)

\(=400:\left\{5\left[360-340\right]\right\}=400:\left(5.20\right)\)

\(=400:100=4\)
