     21;6;260
    Lời giải và giải thích chi tiết:
    60 – [ 120 – 42 – 33² ]
    = 60 – [ 120 – 9² ]
    = 60 – [ 120 – 81 ]
    = 60 – 39
    = 21
       12 : 400 : [ 500 – 125 + 25 . 7 ]
    = 12 : 400 : [ 500 – 125 + 175 ]
    = 12 : 400 : [ 500 – 300 ]
    = 12 : 400 : 200
    = 12 : 2
    = 6
       125 + { 2 . [ 3 . 6² ( 37 – 2 . 17 ) ] } – 3 . 25 . 2021⁰
    = 125 + { 2 . [ 3 . 36 – ( 37 – 2 . 17 ) ] } – 3 . 25 . 1
    = 125  + { 2 . [ 108 – ( 37 – 34 ) ] } -75
    = 125 + { 2 . [ 108 – 3 ] } – 75
    = 125 + { 2 . 105 } – 75
    = 125 + 210 – 75
    = 335 – 75 
    = 260
    Bạn cho mình xin hay nhất
