Math Question: What is the sum of the prime factors of the number 3820?

To find the prime factors of 3820, we divide it by its smallest prime factor, which is 2. We get 3820 ÷ 2 = 1910. By dividing 1910 by 2, we get 1910 ÷ 2 = 955. Again, dividing 955 by 5, the next prime factor, we get 955 ÷ 5 = 191. Finally, dividing 191 by 191 (which is a prime number itself), we obtain 1. Therefore, the prime factors of 3820 are 2, 2, 5, 191. To find the sum of these prime factors: 2 + 2 + 5 + 191 = 200. Thus, the sum of the prime factors of 3820 is 200.

Question: If 3820 is multiplied by 5 and then divided by 2, what is the resulting number?

To find the resulting number, we can multiply 3820 by 5 to get 19100. Further, dividing 19100 by 2 yields 9550. Therefore, by multiplying 3820 by 5 and then dividing by 2, the resulting number is 9550.

Math Question: What is the sum of 3820 when multiplied by 5 and then divided by 2, subtracted by 3000, and then added by the square root of 3820? Math

To find the answer, we follow the steps. Multiply 3820 by 5 to get 19100. Next, divide this result by 2 to obtain 9550. Subtract 3000 from this to get 6550. Finally, find the square root of 3820, which is approximately 61.81. Adding this to 6550 gives a final answer of 6611.81.
