    题型：数学计算
    解:
          59/(1+0.0999999)+59/(1+0.0999999)^2+59/(1+0.0999999)^3+59/(1+0.0999999)^4+(1250+59)/(1+0.0999999)^5
        =59/1.1+59/(1+0.0999999)^2+59/(1+0.0999999)^3+59/(1+0.0999999)^4+(1250+59)/(1+0.0999999)^5
        =59/1.1+59/1.1^2+59/(1+0.0999999)^3+59/(1+0.0999999)^4+(1250+59)/(1+0.0999999)^5
        =59/1.1+59/1.1^2+59/1.1^3+59/(1+0.0999999)^4+(1250+59)/(1+0.0999999)^5
        =59/1.1+59/1.1^2+59/1.1^3+59/1.1^4+(1250+59)/(1+0.0999999)^5
        =59/1.1+59/1.1^2+59/1.1^3+59/1.1^4+1309/(1+0.0999999)^5
        =59/1.1+59/1.1^2+59/1.1^3+59/1.1^4+1309/1.1^5
        =59/1.1+59/1.21+59/1.1^3+59/1.1^4+1309/1.1^5
        =59/1.1+59/1.21+59/1.331+59/1.1^4+1309/1.1^5
        =59/1.1+59/1.21+59/1.331+59/1.4641+1309/1.1^5
        =59/1.1+59/1.21+59/1.331+59/1.4641+1309/1.610510000000001
        =53.636364+59/1.21+59/1.331+59/1.4641+1309/1.610510000000001
        =53.636364+48.760331+59/1.331+59/1.4641+1309/1.610510000000001
        =53.636364+48.760331+44.327573+59/1.4641+1309/1.610510000000001
        =53.636364+48.760331+44.327573+40.297794+1309/1.610510000000001
        =53.636364+48.760331+44.327573+40.297794+812.786012
        =102.396695+44.327573+40.297794+812.786012
        =146.724268+40.297794+812.786012
        =187.022062+812.786012
        =999.808074
    答案:59/(1+0.0999999)+59/(1+0.0999999)^2+59/(1+0.0999999)^3+59/(1+0.0999999)^4+(1250+59)/(1+0.0999999)^5=999.808074
