〖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)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9) 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)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9)
=1.3×(3.66×0.9×0.9+(24+1.5)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9)
=1.3×(3.66×0.9×0.9+25.5×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9)
=1.3×40.1436+1.5×((2.5+2.0)×0.9×0.9)
=1.3×40.1436+1.5×(4.5×0.9×0.9)
=1.3×40.1436+1.5×3.645
=52.18668+1.5×3.645
=52.18668+5.4675
=57.65418 答案:1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9)=57.65418你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
