Math question: What is the square root of the sum of the prime factors of 7784?

To find the prime factors of 7784, we factorize it into primes: 2 × 2 × 1946. The sum of these prime factors is 2 + 2 + 1946 = 1950. Taking the square root of this sum, we get √1950 ≈ 44.15 (rounded to two decimal places). Therefore, the square root of the sum of the prime factors of 7784 is approximately 44.15.

What is the product of the prime factors of 7784?

To find the prime factors of 7784, we can begin by dividing it by the smallest prime numbers: 2, 3, 5, 7, 11, etc. After dividing 7784 successively, we find that its prime factors are 2, 2, 1946. The product of these prime factors can be calculated as 2 * 2 * 1946 = 7784. Hence, the product of the prime factors of 7784 is 7784.

What is the square of the sum of the first three digits of 7784, subtracted by the product of the last digit and the second digit, divided by 10 and rounded to the nearest whole number?

The first three digits of 7784 are 7, 7, and 8. The sum of these digits is 7 + 7 + 8 = 22. The square of 22 is 484. The last digit is 4 and the second digit is 7, so the product of these digits is 4 * 7 = 28. Dividing 28 by 10, we get 2.8. Rounding 2.8 to the nearest whole number gives 3. Subtracting 3 from 484, we get 481 as the final answer.
