( | 10000 | p | − | 10000 | p | × | 5 100 | − | 1000000 | ) | ÷ | 1000000 | = | 20 100 |
方程左边 = | 10000 | p | × | 1 1000000 | − | 10000 | p | × | 5 100 | × | 1 1000000 | − | 1000000 | × | 1 1000000 |
= | 1 100 | p | − | 1 2000 | p | − | 1 |
= | 19 2000 | p | − | 1 |
19 2000 | p | − | 1 | = | 20 100 |
19 2000 | p | = | 20 100 | + | 1 |
19 2000 | p | = | 6 5 |
p | = | 6 5 | ÷ | 19 2000 |
= | 6 5 | × | 2000 19 |
= | 6 | × | 400 19 |
p | = | 2400 19 |
p | = | 126.315789 |
