Answer 1

g) 327 - 27[(3³ + 2020⁰) : 7 - 2]

= 327 - 27[(27 + 1) : 7 - 2]

= 327 - 27(28 : 7 - 2)

= 327 - 27(4 - 2)

= 327 - 27 . 2

= 327 - 54 

= 273

Answer 2

=327-27(28:7-2)

=327-27.2

=273

Answer 3

327 - 27[(3³ + 2020⁰) : 7 - 2 ]

= 327 - 27[(27 + 1 ) : 7 - 2 ]

= 327 - 27[ 28 : 7 - 2 ]

= 327 - 27[ 4 - 2 ]

= 327 - 27 . 2

= 327 - 54
