作业:求算式 40*0.13+60*0.28+80*0.34+100.0|1+120*0.086+140*0.064 的值.
题型:数学计算
解:
40*0.13+60*0.28+80*0.34+100.0|1+120*0.086+140*0.064
=5.2+60*0.28+80*0.34+100.01+120*0.086+140*0.064
=5.2+16.8+80*0.34+100.01+120*0.086+140*0.064
=5.2+16.8+27.2+100.01+120*0.086+140*0.064
=5.2+16.8+27.2+100.01+10.32+140*0.064
=5.2+16.8+27.2+100.01+10.32+8.96
=22+27.2+100.01+10.32+8.96
=49.2+100.01+10.32+8.96
=149.21+10.32+8.96
=159.53+8.96
=168.49 答案:40*0.13+60*0.28+80*0.34+100.0|1+120*0.086+140*0.064=168.49你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
