〖1/1算式〗
    作业：求算式 1/12×(0.85)^2×((2×2.8+0.9)*((32+29.8)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.8)×2.8) 的值.
    题型：数学计算
    解:
          1/12×(0.85)^2×((2×2.8+0.9)*((32+29.8)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.8)×2.8)
        =1/12×0.85^2×((2×2.8+0.9)*((32+29.8)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.8)×2.8)
        =1/12×0.85^2×(6.5*((32+29.8)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.8)×2.8)
        =1/12×0.85^2×(6.5*(61.8-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.8)×2.8)
        =1/12×0.85^2×(6.5*(61.8-174.72/(2.8×2.4))+(32-29.8)×2.8)
        =1/12×0.85^2×(6.5*(61.8-174.72/6.72)+(32-29.8)×2.8)
        =1/12×0.85^2×(6.5*35.8+(32-29.8)×2.8)
        =1/12×0.85^2×(6.5*35.8+2.2×2.8)
        =1/12×0.85^2×238.86
        =1/12×0.7225×238.86
        =0.083333×0.7225×238.86
        =0.060208×238.86
        =14.381283
    答案:1/12×(0.85)^2×((2×2.8+0.9)*((32+29.8)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.8)×2.8)=14.381283
