Question: What is the sum of all the prime factors of 2891?

To find the prime factors of 2891, we first need to divide it by the smallest prime number, which is 2. Dividing 2891 by 2 gives us 1445. Continuing this process, we divide 1445 by 5 to get 289. Dividing 289 by 17 yields 17, which is a prime number. Therefore, the prime factors of 2891 are 2, 5, and 17. Adding them up, we get 2 + 5 + 17 = 24. Thus, the sum of all the prime factors of 2891 is 24.

Math Question: What is the sum of the digits in the number 2891 when each digit is raised to the power of its respective place value and then multiplied by the place value itself?

To find the sum, we'll calculate each digit's value: 2^4 * 4 + 8^3 * 3 + 9^2 * 2 + 1^1 * 1. Hence, 16 * 4 + 512 * 3 + 81 * 2 + 1 = 64 + 1536 + 162 + 1 = 1763. The sum of the digits in the number 2891, raised to the power of their respective place values and multiplied by the place value itself, is 1763.

Math Question: What is the cube root of the product of 2891 and the square root of 2891?

To find the cube root, we first calculate the square root of 2891, which is approximately 53.76. Then, multiplying this by 2891, we get 153686.16. Now, taking the cube root of this product, we find that it is approximately 53.76 or written as an expression: ∛(2891 ∙ √2891) ≈ 53.76. Therefore, the value of the given expression is approximately 53.76.
