    Lời giải và giải thích chi tiết:
    680 : { 34 . [ 60 – ( 18 + 24 : 3 . 2² )]}
    = 680 : { 34 . [ 60 – ( 18 + 24 : 3 . 4 )]}
    = 680 : { 34 . [ 60 – ( 18 + 8 . 4 )]}
    = 680 : { 34 . [ 60 – ( 18 + 32 )]}
    = 680 : { 34 . [ 60 –  50 ]}
    = 680 : { 34 . 10 }
    = 680 : 340
    = 2

  2. 680:{34.[60-(18+24:3.2^2)]}
    = 680:{34.[60-(18+32)]}
    = 680:{34.[60-50]}
    = 680:{34.10}
    = 680:340
    = 2
