作业:求算式 (-5985.99)×750*(1-(1-750/5411.5+((201.5)^2-125^2)/(2×750×5411.5))/(1+(4×125)/(3×5411.5))) 的值.
题型:数学计算
解:
(-5985.99)×750*(1-(1-750/5411.5+((201.5)^2-125^2)/(2×750×5411.5))/(1+(4×125)/(3×5411.5)))
=-5985.99×750*(1-(1-750/5411.5+((201.5)^2-125^2)/(2×750×5411.5))/(1+(4×125)/(3×5411.5)))
=-5985.99×750*(1-(1-750/5411.5+(201.5^2-125^2)/(2×750×5411.5))/(1+(4×125)/(3×5411.5)))
=-5985.99×750*(1-(1-750/5411.5+24977.25/(2×750×5411.5))/(1+(4×125)/(3×5411.5)))
=-5985.99×750*(1-(1-750/5411.5+24977.25/8117250)/(1+(4×125)/(3×5411.5)))
=-5985.99×750*(1-0.864483/(1+(4×125)/(3×5411.5)))
=-5985.99×750*(1-0.864483/(1+500/(3×5411.5)))
=-5985.99×750*(1-0.864483/(1+500/16234.5))
=-5985.99×750*(1-0.864483/1.030799)
=-5985.99×750*0.161347
=-4489492.5*0.161347
