Math question: What is the sum of the digits of the number 2994 when each digit's square root is taken, multiplied by its position in the number?

To find the sum, we take the square root of each digit: √2 + √9 + √9 + √4. Multiplying each square root by its respective position (1, 10, 100, and 1000), we get 2√2 + 3√9 + 9√9 + 4√4. Evaluating these square roots, the expression becomes 2√2 + 3√3 + 9√9 + 4√2. Simplifying, we have 6√2 + 3√3 + 9√9. Since the square roots of 2, 3, and 9 (√2, √3, √9) are irrational, the sum cannot be simplified further in radical form. So, the sum of the digits, when each digit's square root is taken and multiplied by its position, is 6√2 + 3√3 + 9√9.

Question: What is the sum of the prime factors of 2994?

To find the prime factors of 2994, we begin by dividing it by the smallest prime number, 2. We get 2 * 1497. Continuing, 1497 can be divided by 3, resulting in 3 * 499. Finally, 499 is a prime number. So the prime factors of 2994 are 2, 3, and 499. To find their sum, we add: 2 + 3 + 499 = 504. Therefore, the sum of the prime factors of 2994 is 504.

Math question: What is the sum of the digits of the product of 2994 and its square?

To find the product of 2994 and its square, calculate 2994 multiplied by 2994². This gives us a result of approximately 26947130032. To find the sum of the digits in this number, we add each digit individually. The sum is 2+6+9+4+7+1+3+0+0+3+2 = 37. Therefore, the sum of the digits in the product of 2994 and its square is 37.
