Math question: What is the sum of the digits of the square root of 2979, rounded to the nearest whole number?

To find the square root of 2979, we take the square root of 2979 ≈ 54.597. Summing the digits, we get 5 + 4 + 5 + 9 + 7 ≈ 30. Rounding 30 to the nearest whole number gives us 30. Hence, the answer to the question is 30.

Math question: What is the smallest prime factor of the number obtained by multiplying 2979 by 4 and adding 3?

To find the number, perform the operation (2979 × 4) + 3 = 11916 + 3 = 11919. To determine the smallest prime factor of 11919, we can check divisibility by primes. Considering primes up to the square root of 11919 (roughly 109.2), we find that 11919 is not divisible by 2, 3, 5, 7, or 11. However, dividing by 13 yields an exact quotient, indicating that 13 is the smallest prime factor of 11919.

Math question: What is the sum of the prime factors of the number 2979?

To find the prime factors of 2979, we break it down into its prime factors as 3 × 7 × 142. The sum of these prime factors is 3 + 7 + 142 = 152.
