    作业：求算式 180×sqrt(9÷1.67×1.67+1)÷3÷sqrt(99.4×99.4×9+1)÷sqrt(1.25)÷sqrt(0.0084×0.0084×9+1) 的值.
    题型：数学计算
    解:
          180×sqrt(9÷1.67×1.67+1)÷3÷sqrt(99.4×99.4×9+1)÷sqrt(1.25)÷sqrt(0.0084×0.0084×9+1)
        =180×sqrt10.000001÷3÷sqrt(99.4×99.4×9+1)÷sqrt(1.25)÷sqrt(0.0084×0.0084×9+1)
        =180×sqrt10.000001÷3÷sqrt88924.24÷sqrt(1.25)÷sqrt(0.0084×0.0084×9+1)
        =180×sqrt10.000001÷3÷sqrt88924.24÷sqrt1.25÷sqrt(0.0084×0.0084×9+1)
        =180×sqrt10.000001÷3÷sqrt88924.24÷sqrt1.25÷sqrt1.000639
        =180×3.162278÷3÷sqrt88924.24÷sqrt1.25÷sqrt1.000639
        =180×3.162278÷3÷298.201677÷sqrt1.25÷sqrt1.000639
        =180×3.162278÷3÷298.201677÷1.118034÷sqrt1.000639
        =180×3.162278÷3÷298.201677÷1.118034÷1.000319
        =569.21004÷3÷298.201677÷1.118034÷1.000319
        =189.73668÷298.201677÷1.118034÷1.000319
        =0.63627÷1.118034÷1.000319
        =0.569097÷1.000319
        =0.568916
    答案:180×sqrt(9÷1.67×1.67+1)÷3÷sqrt(99.4×99.4×9+1)÷sqrt(1.25)÷sqrt(0.0084×0.0084×9+1)=0.568916
