What is the square root of 6690 plus the product of 2 and the cube root of 6690, rounded to the nearest whole number?

The square root of 6690 is approximately 81.8 (rounded to the nearest tenth). The cube root of 6690 is approximately 19.7 (rounded to the nearest tenth). The product of 2 and the cube root of 6690 is approximately 2 times 19.7, which equals 39.4. Adding 81.8 and 39.4 gives us approximately 121.2. Rounding this to the nearest whole number, the answer is 121.

Question: What is the smallest positive multiple of 6690 that can be expressed as the sum of two distinct prime numbers?

To find the smallest multiple of 6690 that is the sum of two distinct prime numbers, we need to identify the prime numbers and check their sums. The prime factors of 6690 are 2, 3, 5, 223. To form the sum of two distinct primes, there are a few possibilities: 2+3, 2+5, 2+223, 3+5, 3+223, or 5+223. Calculating these sums yields 5, 7, 225, 8, 226, and 228, respectively. Since we are looking for the smallest positive multiple of 6690, we discard sums 5 and 7. The smallest multiple is then 6690*2 = 13380, which can be expressed as 6690+6690 or 3+223+6690. Hence, the answer is 13380.

What is the sum of the prime factors of 6690, excluding the number 6690 itself?

To find the prime factors of 6690, we factorize 6690 into its prime factors, which are 2, 3, 5, 223. Then, we sum these prime factors, excluding 6690, to get 2 + 3 + 5 + 223 = 233.
