Question: What is the square root of the product of 2639 and the sum of the digits of 2639 multiplied by 2 and divided by 5?

In order to find the solution, let's break it down step by step. First, calculate the sum of the digits of 2639, which is 2+6+3+9 = 20. Next, multiply this sum by 2, giving us 20 * 2 = 40. Then, multiply the result by 2639: 40 * 2639 = 105560. Now, taking the square root of the product gives us √105560. On simplification, the square root of 105560 is 324.781. Therefore, the answer is 324.781.

Math Question: What is the result of multiplying 2639 by 7, dividing it by 2, and then subtracting 45?

To find the result, we first multiply 2639 by 7, which equals 18473. Then, we divide this by 2 to get 9236.5. Finally, we subtract 45 from this value, resulting in 9191.5. Therefore, the answer is 9191.5.

Math Question: If the number 2639 is divided by 127 and then multiplied by 18, what is the result?

To find the result, we divide 2639 by 127, which gives 20.7480 (rounded to 4 decimal places). Then, we multiply this quotient by 18, which equals 373.4640 (rounded to 4 decimal places). Therefore, the result of dividing 2639 by 127 and then multiplying by 18 is 373.4640.
