Math Question: What is the sum of the digits of the number 428, when each digit is raised to the power of the number itself, then added together?

To find the sum, we raise each digit to the power of itself: 4^4 + 2^2 + 8^8. This simplifies to 256 + 4 + 16777216. Adding these values, we get 16777476. Thus, the sum of the digits of 428 is 16777476.

What is the result when 428 is added to the sum of its digits multiplied by their difference divided by the square root of 428?

To find the solution, we first calculate the sum of the digits: 4 + 2 + 8 = 14. Next, we find the difference between the digits: 8 - 4 = 4. Taking the square root of 428, we get approximately 20.691. Now, multiplying the digit difference by the sum (4 * 14 = 56) and dividing it by the square root (56 / 20.691), we find approximately 2.704. Adding this value to 428, the final result is approximately 430.704.

What is the sum of the ones, tens, and hundreds digits of the number 428?

The ones digit is 8, the tens digit is 2, and the hundreds digit is 4. Adding these together, we get 8+2+4 = 14.
