〖1/1算式〗
作业:求算式 100/(1+7%)+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4 的值.
题型:数学计算
解:
100/(1+7%)+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/1.07^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/1.07^3+100/1.07^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/1.07^3+100/1.07^4+1000/1.07^4
=100/1.07+100/1.1449+100/1.07^3+100/1.07^4+1000/1.07^4
=100/1.07+100/1.1449+100/1.225043+100/1.07^4+1000/1.07^4
=100/1.07+100/1.1449+100/1.225043+100/1.31079601+1000/1.07^4
=100/1.07+100/1.1449+100/1.225043+100/1.31079601+1000/1.31079601
=93.457944+100/1.1449+100/1.225043+100/1.31079601+1000/1.31079601
=93.457944+87.343873+100/1.225043+100/1.31079601+1000/1.31079601
=93.457944+87.343873+81.629788+100/1.31079601+1000/1.31079601
=93.457944+87.343873+81.629788+76.289521+1000/1.31079601
=93.457944+87.343873+81.629788+76.289521+762.895212
=180.801817+81.629788+76.289521+762.895212
=262.431605+76.289521+762.895212
=338.721126+762.895212
=1101.616338 答案:100/(1+7%)+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4=1101.616338你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
