〖1/1算式〗
作业:求算式 (985.5×0.59)/((0.59)^2×4+(0.48)^2×4+(0.21)^2×4+(0.2)^2×4) 的值.
题型:数学计算
解:
(985.5×0.59)/((0.59)^2×4+(0.48)^2×4+(0.21)^2×4+(0.2)^2×4)
=581.445/((0.59)^2×4+(0.48)^2×4+(0.21)^2×4+(0.2)^2×4)
=581.445/(0.59^2×4+(0.48)^2×4+(0.21)^2×4+(0.2)^2×4)
=581.445/(0.59^2×4+0.48^2×4+(0.21)^2×4+(0.2)^2×4)
=581.445/(0.59^2×4+0.48^2×4+0.21^2×4+(0.2)^2×4)
=581.445/(0.59^2×4+0.48^2×4+0.21^2×4+0.2^2×4)
=581.445/2.6504
=219.380094 答案:(985.5×0.59)/((0.59)^2×4+(0.48)^2×4+(0.21)^2×4+(0.2)^2×4)=219.380094你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
