What is the sum of the digits of the number 3689?

The sum of the digits of 3689 is 3 + 6 + 8 + 9 = 26.

What is the sum of the digits in the number 3689?

To find the sum of the digits, we separate the number into its individual digits: 3, 6, 8, and 9. Adding these digits together gives us 3 + 6 + 8 + 9 = 26. Therefore, the sum of the digits in the number 3689 is 26.

Math question: What is the sum of twice the square root of 3689 and the cube of its tens digit minus the product of its ones and thousands digits divided by its hundreds digit?

To solve this, we start by identifying the digits of the number 3689. The ones digit is 9, the tens digit is 8, the hundreds digit is 6, and the thousands digit is 3. Now, let's calculate each component. The square root of 3689 is approximately 60.815. Twice this value is approximately 121.63. The cube of the tens digit (8) is 512. The product of the ones digit (9) and the thousands digit (3) is 27. Dividing the product (27) by the hundreds digit (6) results in 4.5. Now, let's combine these components according to the original question: 121.63 + 512 - 4.5 = 629.13 Therefore, the answer to the given math question is approximately 629.13.
