What is the sum of the digits of the number 5645 when each digit is squared and added together?

The sum of the digits of 5645, when each digit is squared and added together, is 91. Explanation: To find the sum of the squared digits, we can take each digit individually. The first digit is 5, so 5 squared is 25. The second digit is 6, so 6 squared is 36. The third digit is 4, so 4 squared is 16. Finally, the last digit is 5, so 5 squared is 25. Adding these results together (25 + 36 + 16 + 25) gives us a sum of 102.

Math question: What is the result when you multiply 5645 by the sum of its digits?

To find the sum of the digits of 5645, we add 5 + 6 + 4 + 5, which equals 20. Now, multiplying 5645 by the sum, we have 5645 × 20 = 112,900. Therefore, the product of 5645 and the sum of its digits is 112,900.

Math question: If 5645 is multiplied by 367 and then divided by the square root of 25, what is the final result?

To find the answer, we first calculate 5645 multiplied by 367, which equals 2,070,515. Next, we determine the square root of 25, which is 5. Finally, dividing 2,070,515 by 5 gives us the result of 414,103. Thus, after performing the multiplication and division operations, the final result is 414,103.
