作业:求算式 3000/(1.15)+3000/1.15^2+3000/1.15^3+3000/1.15^4-10000 的值.
题型:数学计算
解:
3000/(1.15)+3000/1.15^2+3000/1.15^3+3000/1.15^4-10000
=3000/1.15+3000/1.15^2+3000/1.15^3+3000/1.15^4-10000
=3000/1.15+3000/1.3225+3000/1.15^3+3000/1.15^4-10000
=3000/1.15+3000/1.3225+3000/1.520875+3000/1.15^4-10000
=3000/1.15+3000/1.3225+3000/1.520875+3000/1.749006249999999-10000
=2608.695652+3000/1.3225+3000/1.520875+3000/1.749006249999999-10000
=2608.695652+2268.431002+3000/1.520875+3000/1.749006249999999-10000
=2608.695652+2268.431002+1972.548697+3000/1.749006249999999-10000
=2608.695652+2268.431002+1972.548697+1715.259737-10000
=4877.126654+1972.548697+1715.259737-10000
=6849.675351+1715.259737-10000
=8564.935088-10000
=-1435.064912 答案:3000/(1.15)+3000/1.15^2+3000/1.15^3+3000/1.15^4-10000=-1435.064912你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
