Math question: What is the sum of the digits of the number 9811 multiplied by 3, divided by 5, added to 123, and then squared?

To find the sum of the digits of 9811, we first add 9+8+1+1, which equals 19. Next, we multiply 19 by 3 to get 57. Dividing 57 by 5 gives us 11.4. Adding 123 to 11.4 results in 134.4. Finally, squaring 134.4 gives us 18,091.36. Therefore, the answer is 18,091.36.

Question: What is the value of 9811 when it is divided by 3 and then multiplied by 7, subtracted by its square root, and finally added to twice its cube root?

To find the value of 9811, we'll follow the given operations step by step. First, dividing 9811 by 3 gives us 3270.33. Multiplying this result by 7 yields 22892.33. Now, let's calculate the square root of 9811, which is approximately 99.05. Subtracting this square root from our previous result gives us 22793.28. Finally, let's calculate the cube root of 9811, which is approximately 21.37. Doubling this cube root gives us 42.74. Adding this value to the previous result gives us the final answer of 22836.02. Hence, the value of 9811 after the given mathematical operations is approximately 22836.02.

What is the sum of all even numbers between 1000 and 9999, excluding 9811?

To find the sum of even numbers in that range, we first calculate the number of even numbers using floor division: (9999-1000+1) // 2 = 4500. Since the sequence is arithmetic, we can use the sum formula: S = (n/2)(a+l), where n is the number of terms, a is the first term, and l is the last term. Here, a = 1000 (the smallest even number in the range) and l = 9998 (the largest even number before 9811). So, the sum is S = (4500/2)(1000+9998) = 2250 * 10998 = 24,744,500. Thus, the sum of all even numbers between 1000 and 9999, excluding 9811, is 24,744,500.
