    解:
          7.280673*ln756.5+2×(-1.434148)×10^(-3)×756.5+3/2×2.3482926×10^(-7)×756.5^(2)
        =7.280673*ln756.5+2×(-1.434148)×10^(-3)×756.5+3/2×2.3482926×10^(-7)×756.5^(2)
        =7.280673*ln756.5+2×(-1.434148)×10^(-3)×756.5+3/2×2.3482926×10^(-7)×756.5^(2)
        =7.280673*ln756.5+2×(-1.434148)×10^-3×756.5+3/2×2.3482926×10^(-7)×756.5^(2)
        =7.280673*ln756.5+2×(-1.434148)×10^-3×756.5+3/2×2.3482926×10^-7×756.5^2
        =7.280673*6.628703+2×-1.434148×10^-3×756.5+3/2×2.3482926×10^-7×756.5^2
        =7.280673*6.628703+2×(-1.434148)×0.001×756.5+3/2×2.3482926×10^(-7)×756.5^2
        =7.280673*6.628703+2×(-1.434148)×0.001×756.5+3/2×2.3482926×0.0000001×756.5^2
        =7.280673*6.628703+2×(-1.434148)×0.001×756.5+3/2×2.3482926×0.0000001×572292.25
        =48.261419+2×(-1.434148)×0.001×756.5+3/2×2.3482926×0.0000001×572292.25
        =48.261419+(-2.868296)×0.001×756.5+3/2×2.3482926×0.0000001×572292.25
        =48.261419+(-0.002868)×756.5+3/2×2.3482926×0.0000001×572292.25
        =48.261419+(-2.169642)+3/2×2.3482926×0.0000001×572292.25
        =48.261419+-2.169642+1.5×2.3482926×0.0000001×572292.25
        =48.261419+-2.169642+3.522439×0.0000001×572292.25
        =48.261419+-2.169642+0×572292.25
        =48.261419+-2.169642+0
        =46.091777+0
        =46.091777
    答案:7.280673*ln756.5+2×(-1.434148)×10^(-3)×756.5+3/2×2.3482926×10^(-7)×756.5^(2)=46.091777
