[1/1 Formula]
    Work: Calculate the value of equation (20+19.4×1.79+19.2×2.9+19.8×3.4)×0.52-2×54×0.72 .
    Question type: Mathematical calculation
    Solution:
          (20+19.4×1.79+19.2×2.9+19.8×3.4)×0.52-2×54×0.72
        =177.726×0.52-2×54×0.72
        =92.41752-2×54×0.72
        =92.41752-108×0.72
        =92.41752-77.76
        =14.65752

    Answer:(20+19.4×1.79+19.2×2.9+19.8×3.4)×0.52-2×54×0.72=14.65752
