〖1/1算式〗
作业:求算式 500×12×(132.77-0.5×12)+2×(132.77-12)×12×0.5×(132.77-12) 的值.
题型:数学计算
解:
500×12×(132.77-0.5×12)+2×(132.77-12)×12×0.5×(132.77-12)
=500×12×126.77+2×(132.77-12)×12×0.5×(132.77-12)
=500×12×126.77+2×120.77×12×0.5×(132.77-12)
=500×12×126.77+2×120.77×12×0.5×120.77
=6000×126.77+2×120.77×12×0.5×120.77
=760620+2×120.77×12×0.5×120.77
=760620+241.54×12×0.5×120.77
=760620+2898.48×0.5×120.77
=760620+1449.24×120.77
=760620+175024.7148
=935644.7148 答案:500×12×(132.77-0.5×12)+2×(132.77-12)×12×0.5×(132.77-12)=935644.7148你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
