    Lời giải và giải thích chi tiết:
    = [(75 + 175).5^4 ] : (20.25.25.5 – 625.75)
    = (250.5^4 ) : [ 625.(100 – 75)]
    = (250.5^4) : (5^4. 25)
    = 250 : 25
    = 10

  2. $( 75 . 5^4 + 175 . 5^4 ) : ( 20 . 25 . 125 – 625 . 75)$
    $= [5^4 (75+175)] : (20.25.125-125.5.25.3)$
    $= (625.250):(625.25) = 10$
