作业:求算式 1/(250×sqrt(0.25×84.22×84.22+1)/(84.22)/sqrt(0.0009×84.22×84.22+1)/sqrt(0.0047×0.0047×84.22×84.22+1)/sqrt(100×84.22×84.22+1)) 的值.
题型:数学计算
解:
1/(250×sqrt(0.25×84.22×84.22+1)/(84.22)/sqrt(0.0009×84.22×84.22+1)/sqrt(0.0047×0.0047×84.22×84.22+1)/sqrt(100×84.22×84.22+1))
=1/(250×sqrt1774.2521/(84.22)/sqrt(0.0009×84.22×84.22+1)/sqrt(0.0047×0.0047×84.22×84.22+1)/sqrt(100×84.22×84.22+1))
=1/(250×sqrt1774.2521/84.22/sqrt(0.0009×84.22×84.22+1)/sqrt(0.0047×0.0047×84.22×84.22+1)/sqrt(100×84.22×84.22+1))
=1/(250×sqrt1774.2521/84.22/sqrt7.383708/sqrt(0.0047×0.0047×84.22×84.22+1)/sqrt(100×84.22×84.22+1))
=1/(250×sqrt1774.2521/84.22/sqrt7.383708/sqrt1.15606/sqrt(100×84.22×84.22+1))
=1/(250×sqrt1774.2521/84.22/sqrt7.383708/sqrt1.15606/sqrt709301.84)
=1/0.050815
=19.679229 答案:1/(250×sqrt(0.25×84.22×84.22+1)/(84.22)/sqrt(0.0009×84.22×84.22+1)/sqrt(0.0047×0.0047×84.22×84.22+1)/sqrt(100×84.22×84.22+1))=19.679229你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
