  1. Giải đáp:
    $-2^{5}$ + {[(-69) : 3 + 53]} . (-2) – 8
    = (-32) + {[-(69 : 3) + 53]} . (-2) + (-8)
    = (-32) + {[(-23) + 53]} . -(2 + 8)
    = (-32) + {[+53 – 23]} . (-10)
    = (-32) + 30 . (-10)
    = (-32) + -(30 . 10)
    = (-32) + (-20)
    = -(32 + 20)
    = -52
     

  2. Lời giải chi tiết:
    (-2)^5+[(-69):3+53].(-2)-8
    =-32+(-23+53).(-2)-8
    =-32+30.(-2)-8
    =(-32-8)+(-60)
    =-40+(-60)
    =-100
