What is the sum of the digits of the number 7639 multiplied by the difference between its hundreds digit and tens digit, divided by twice the units digit, subtracted by four times the thousands digit, squared, plus three times the tens digit?

To solve this question, we first find the sum of the digits of 7639, which is 7 + 6 + 3 + 9 = 25. Then, we calculate the difference between its hundreds digit (6) and tens digit (3), which equals 3. Taking the sum of the digits (25) multiplied by this difference (3), the result is 75. Next, we divide this value by twice the units digit (9), which gives us 8.3333 (repeating). After that, we subtract four times the thousands digit (7), which is -28.3333 (repeating). Squaring this result, it becomes 803.0864, approximately. Finally, we add three times the tens digit (3), resulting in 806.0864. Therefore, the answer is 806.0864.
