  1. Giải đáp:
    2 . 5³ – 36 : 3 = 2 . 125 – 12 = 250 – 12 = 238
    3³ . 19 – 3³ . 12 = 3³ . (19 – 12) = 27 . 7 = 189
    17 . 131 + 69 . 17 = 17 . (131 + 69) = 17 . 200 = 3400
    Chúc học tốt!!!
     
     

  2. a, 2.5^3-36:3
    =2.125-12
    =250-12=238
    b,
    3^3.19-3^3.12
    =3^3.(19-12)
    =27.7=189
    c,
    17.131+69.17
    =17.(131+69)
    =17.200=3400
