| m | = | 431 100 | ÷ | ( | 431 100 | − | 5 2 | ) |
| Multiply both sides of the equation by: | ( | 431 100 | − | 5 2 | ) |
| m | ( | 431 100 | − | 5 2 | ) | = | 431 100 |
| m | × | 431 100 | − | m | × | 5 2 | = | 431 100 |
181 100 | m | = | 431 100 |
| m | = | 431 100 | ÷ | 181 100 |
| = | 431 100 | × | 100 181 |
| = | 431 | × | 1 181 |
| m | = | 431 181 |
| m | = | 2.381215 |
