  1. 360: 12.2 +[ (11- 4)^3 – 343]. 2020^2021
    =30.2+(7^3-343).2020^2021
    =60+(343-343).2020^2021
    =60+0.2020^2021
    =60+0
    =60
     

  2. 360 : 12 . 2 + [ ( 11 – 4 )^3 – 343 ] . 2020^2021
    = 30 . 2 + [ 7^3 – 343 ] . 2020^2021
    = 60 + [ 343 – 343 ] . 2020^2021
    = 60 + 0 . 2020^2021
    = 60 + 0
    = 60
