〖1/1算式〗
    作业：求算式 -37500+(17300/(1+0.11))+(16200/(1+0.11)^2)+(13800/(1+0.11)^3)+(7600/(1+0.11)^4) 的值.
    题型：数学计算
    解:
          -37500+(17300/(1+0.11))+(16200/(1+0.11)^2)+(13800/(1+0.11)^3)+(7600/(1+0.11)^4)
        =-37500+(17300/1.11)+(16200/(1+0.11)^2)+(13800/(1+0.11)^3)+(7600/(1+0.11)^4)
        =-37500+15585.585586+(16200/(1+0.11)^2)+(13800/(1+0.11)^3)+(7600/(1+0.11)^4)
        =-37500+15585.585586+(16200/1.11^2)+(13800/(1+0.11)^3)+(7600/(1+0.11)^4)
        =-37500+15585.585586+13148.283419+(13800/(1+0.11)^3)+(7600/(1+0.11)^4)
        =-37500+15585.585586+13148.283419+(13800/1.11^3)+(7600/(1+0.11)^4)
        =-37500+15585.585586+13148.283419+10090.441062+(7600/(1+0.11)^4)
        =-37500+15585.585586+13148.283419+10090.441062+(7600/1.11^4)
        =-37500+15585.585586+13148.283419+10090.441062+5006.355404
        =-21914.414414+13148.283419+10090.441062+5006.355404
        =-8766.130995+10090.441062+5006.355404
        =1324.310067+5006.355404
        =6330.665471
    答案:-37500+(17300/(1+0.11))+(16200/(1+0.11)^2)+(13800/(1+0.11)^3)+(7600/(1+0.11)^4)=6330.665471
