Question

125 - 4 [ 3 - 7 . (-2) ]

18 + {  [ 3^3 - (-54) ] }

3^8 : 3^5 + 2021^0 - ( 95 - 100) ^2

Answer 1

125 - 4 [ 3 - 7 . ( - 2 ) ]

= 125 - 4 [ 3 + 14 ]

= 125 - 68

= 57

18 + [ 3^3 - ( - 54 ) ]

= 18 + 81

= 99

3^8 : 3^5 + 2021^0 - ( 95 - 100 )^2

= 3^3 + 1 - 25

= 27 - 24

= 3

Answer 2

\(125-4\left[3-7.\left(-2\right)\right]=57\)

\(18+\left\{\left[3^3-\left(-54\right)\right]\right\}=99\)

\(3^8:3^5+2021^0-\left(95-100\right)^2=3\)
