〖1/1算式〗
    作业：求算式 √((2×2.15×247.386×1000)/(1×64.149^3)×(3.21+1)/(3.21))×2.46×189.8×0.713×0.987 的值.
    题型：数学计算
    解:
          √((2×2.15×247.386×1000)/(1×64.149^3)×(3.21+1)/(3.21))×2.46×189.8×0.713×0.987
        =√(1063759.8/(1×64.149^3)×(3.21+1)/(3.21))×2.46×189.8×0.713×0.987
        =√(1063759.8/263979.1779×(3.21+1)/(3.21))×2.46×189.8×0.713×0.987
        =√(1063759.8/263979.1779×4.21/(3.21))×2.46×189.8×0.713×0.987
        =√(1063759.8/263979.1779×4.21/3.21)×2.46×189.8×0.713×0.987
        =√5.285073×2.46×189.8×0.713×0.987
        =2.298929×2.46×189.8×0.713×0.987
        =5.655365×189.8×0.713×0.987
        =1073.388277×0.713×0.987
        =765.325842×0.987
        =755.376606
    答案:√((2×2.15×247.386×1000)/(1×64.149^3)×(3.21+1)/(3.21))×2.46×189.8×0.713×0.987=755.376606
