Math question: What is the sum of all the digits in the number 5445 when squared, divided by 11, multiplied by 7, and then subtracted by the product of 5 and the difference between the largest and smallest digits?

To find the sum of the digits in 5445, we square it, resulting in 29647025. Dividing this by 11 gives us 2695184.0909. Multiplying it by 7, we get 18866288.6364. Knowing that the largest digit is 5 and the smallest digit is 4, we calculate the difference as 5 - 4 = 1. Multiplying this by 5 gives us 5. Finally, subtracting this from 18866288.6364 yields an answer of 18866283.6364.

Math question: What is the sum of the digits of the number 5445 multiplied by the sum of the first 10 prime numbers, divided by the square root of 5445?

To find the sum of the digits of 5445, we add 5+4+4+5, which equals 18. The sum of the first 10 prime numbers (2+3+5+7+11+13+17+19+23+29) is 129. The square root of 5445 is approximately 73.824. So, the equation becomes: (18 x 129) ÷ 73.824 = 31.5 (rounded to one decimal place) Therefore, the answer is 31.5.

Math question: What is the sum of the digits in the number 5,445 multiplied by the square root of 5,445, divided by the sum of the prime factors of 5,445?

To find the sum of the digits in 5,445, we add 5 + 4 + 4 + 5 = 18. The prime factors of 5,445 are 3, 5, 7, and 13, so their sum is 3 + 5 + 7 + 13 = 28. Now, multiplying 18 by the square root of 5,445 gives us 18 √5445. By substituting the values and simplifying, the expression becomes 18 × √5445 / 28. Evaluating this, we find that 18 × √5445 / 28 ≈ 22.42. Therefore, the answer is approximately 22.42.
