[1/1 Formula]
    Work: Calculate the value of equation (20+18.5×1.5+19.8×3.8+19.4×1.8+18.8×1.2+18.8×6.8)×0.28-2×0×√0.28 .
    Question type: Mathematical calculation
    Solution:
          (20+18.5×1.5+19.8×3.8+19.4×1.8+18.8×1.2+18.8×6.8)×0.28-2×0×√0.28
        =308.31×0.28-2×0×√0.28
        =308.31×0.28-2×0×0.52915
        =86.3268-2×0×0.52915
        =86.3268-0×0.52915
        =86.3268-0
        =86.3268

    Answer:(20+18.5×1.5+19.8×3.8+19.4×1.8+18.8×1.2+18.8×6.8)×0.28-2×0×√0.28=86.3268
