[1/1 Formula]
    Work: Calculate the value of equation (20+18.5×1.525+19.8×3.8+19.4×1.8+18.8×1.475)×0.49-2×17×√0.49 .
    Question type: Mathematical calculation
    Solution:
          (20+18.5×1.525+19.8×3.8+19.4×1.8+18.8×1.475)×0.49-2×17×√0.49
        =186.1025×0.49-2×17×√0.49
        =186.1025×0.49-2×17×0.7
        =91.190225-2×17×0.7
        =91.190225-34×0.7
        =91.190225-23.8
        =67.390225

    Answer:(20+18.5×1.525+19.8×3.8+19.4×1.8+18.8×1.475)×0.49-2×17×√0.49=67.390225
