〖1/1算式〗
作业:求算式 1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35) 的值.
题型:数学计算
解:
1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×(3.66×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×(3.66×0.9×0.9+25.5×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×23.6196+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×23.6196+1.5×(4.5×0.9×0.9+1.35)
=1.3×23.6196+1.5×4.995
=30.70548+1.5×4.995
=30.70548+7.4925
=38.19798 答案:1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)=38.19798你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
