〖1/1算式〗
    作业：求算式 3000/0.82875%*(1-1/(1+0.82875%)^20)+100000/(1+0.82875%)^20 的值.
    题型：数学计算
    解:
          3000/0.82875%*(1-1/(1+0.82875%)^20)+100000/(1+0.82875%)^20
        =3000/0.82875%*(1-1/1.008287^20)+100000/(1+0.82875%)^20
        =3000/0.82875%*0.152155+100000/(1+0.82875%)^20
        =3000/0.82875%*0.152155+100000/1.008287^20
        =3000/0.008287*0.152155+100000/1.008287^20
        =3000/0.008287*0.152155+100000/1.179460377779569
        =362012.791119*0.152155+100000/1.179460377779569
        =55082.056233+100000/1.179460377779569
        =55082.056233+84784.53527
        =139866.591503
    答案:3000/0.82875%*(1-1/(1+0.82875%)^20)+100000/(1+0.82875%)^20=139866.591503
