    解:
          7.280673*ln417.42+2×(-1.434148×10^(-3))×417.42+3/2×2.3482926×10^(-7)×(417.42)^2
        =7.280673*ln417.42+2×(-1.434148×10^(-3))×417.42+3/2×2.3482926×10^(-7)×(417.42)^2
        =7.280673*ln417.42+2×(-0.001434)×417.42+3/2×2.3482926×10^(-7)×(417.42)^2
        =7.280673*ln417.42+2×(-0.001434)×417.42+3/2×2.3482926×10^(-7)×(417.42)^2
        =7.280673*ln417.42+2×(-0.001434)×417.42+3/2×2.3482926×10^-7×417.42^2
        =7.280673*6.034093+2×-0.001434×417.42+3/2×2.3482926×10^-7×417.42^2
        =7.280673*6.034093+2×(-0.001434)×417.42+3/2×2.3482926×0.0000001×417.42^2
        =7.280673*6.034093+2×(-0.001434)×417.42+3/2×2.3482926×0.0000001×174239.456400000024587
        =43.932258+2×(-0.001434)×417.42+3/2×2.3482926×0.0000001×174239.456400000024587
        =43.932258+(-0.002868)×417.42+3/2×2.3482926×0.0000001×174239.456400000024587
        =43.932258+(-1.197161)+3/2×2.3482926×0.0000001×174239.456400000024587
        =43.932258+-1.197161+1.5×2.3482926×0.0000001×174239.456400000024587
        =43.932258+-1.197161+3.522439×0.0000001×174239.456400000024587
        =43.932258+-1.197161+0×174239.456400000024587
        =43.932258+-1.197161+0
        =42.735097+0
        =42.735097
    答案:7.280673*ln417.42+2×(-1.434148×10^(-3))×417.42+3/2×2.3482926×10^(-7)×(417.42)^2=42.735097
