〖1/1算式〗
作业:求算式 12000*60^3+9000*80^3/(60+80)^3+3/140*(1/12000*60+1/9000*80)^-1 的值.
题型:数学计算
解:
12000*60^3+9000*80^3/(60+80)^3+3/140*(1/12000*60+1/9000*80)^-1
=12000*60^3+9000*80^3/140^3+3/140*(1/12000*60+1/9000*80)^-1
=12000*60^3+9000*80^3/140^3+3/140*0.01386^-1
=12000*216000+9000*80^3/140^3+3/140*0.01386^(-1)
=12000*216000+9000*512000/140^3+3/140*0.01386^(-1)
=12000*216000+9000*512000/2744000+3/140*0.01386^(-1)
=12000*216000+9000*512000/2744000+3/140*72.150072150072148
=2592000000+9000*512000/2744000+3/140*72.150072150072148
=2592000000+4608000000/2744000+3/140*72.150072150072148
=2592000000+1679.300292+3/140*72.150072150072148
=2592000000+1679.300292+0.021429*72.150072150072148
=2592000000+1679.300292+1.546104
=2592001679.300292+1.546104
=2592001680.846396 答案:12000*60^3+9000*80^3/(60+80)^3+3/140*(1/12000*60+1/9000*80)^-1=2592001680.846396你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
