[1/1 Formula]
    Work: Calculate the value of equation -1500+400*(1+15%)^15-1/15%*(1+15%)^15 .
    Question type: Mathematical calculation
    Solution:
          -1500+400*(1+15%)^15-1/15%*(1+15%)^15
        =-1500+400*1.15^15-1/15%*(1+15%)^15
        =-1500+400*1.15^15-1/15%*1.15^15
        =-1500+400*1.15^15-1/0.15*1.15^15
        =-1500+400*8.137061629162321-1/0.15*1.15^15
        =-1500+400*8.137061629162321-1/0.15*8.137061629162321
        =-1500+3254.824652-1/0.15*8.137061629162321
        =-1500+3254.824652-6.666667*8.137061629162321
        =-1500+3254.824652-54.24708
        =1754.824652-54.24708
        =1700.577572

    Answer:-1500+400*(1+15%)^15-1/15%*(1+15%)^15=1700.577572
