Question

Answer 1

\(a,=2022\left(168-68\right)=2022\cdot100=202200\\ b,=1005-5\cdot25\left(2^3-2^2\right)=1005-125\cdot4=1005-500=505\)

Answer 2

a,=2022(168−68)=2022⋅100=202200

b,=1005−5⋅25(23−22)=1005−125⋅4=1005−500=505

Answer 3

B) = 2022 . ( 168 - 68 )

= 2022 . 100

= 202000

c) =1005 - 5 . [ 25 . 8 - 2^2 . 25 ]

= 1005 - 5 . [ 25 . 8 - 4 . 25 ]

= 1005 - 5 . [ 200 - 100 ]

= 1005 - 5 . 100

= 1005 - 500

= 505
