作业:求算式 (-5517.2)×675×(1-(1-675/4911.5+((201.5)^2-125^2)/(2×675×4911.5))/(1+(4×125)/(3×4911.5))) 的值.
题型:数学计算
解:
(-5517.2)×675×(1-(1-675/4911.5+((201.5)^2-125^2)/(2×675×4911.5))/(1+(4×125)/(3×4911.5)))
=-5517.2×675×(1-(1-675/4911.5+((201.5)^2-125^2)/(2×675×4911.5))/(1+(4×125)/(3×4911.5)))
=-5517.2×675×(1-(1-675/4911.5+(201.5^2-125^2)/(2×675×4911.5))/(1+(4×125)/(3×4911.5)))
=-5517.2×675×(1-(1-675/4911.5+24977.25/(2×675×4911.5))/(1+(4×125)/(3×4911.5)))
=-5517.2×675×(1-(1-675/4911.5+24977.25/6630525)/(1+(4×125)/(3×4911.5)))
=-5517.2×675×(1-0.866334/(1+(4×125)/(3×4911.5)))
=-5517.2×675×(1-0.866334/(1+500/(3×4911.5)))
=-5517.2×675×(1-0.866334/(1+500/14734.5))
=-5517.2×675×(1-0.866334/1.033934)
=-5517.2×675×0.162099
=-3724110×0.162099
