Math question: What is the sum of 641 when multiplied by the cube root of 641 and then divided by the square root of 641, rounded to the nearest whole number?

To find the answer, we first calculate the cube root of 641 which is approximately 8.003. Next, we compute the square root of 641 which is approximately 25.317. Now, multiplying 641 by 8.003 gives us 5126.843, and dividing that by 25.317 results in 202.503. Rounding this to the nearest whole number, we get 203 as the answer to the original question.

Math Question: What is the sum of the prime factors of 641?

To find the answer, we need to determine the prime factors of 641. Since it is a prime number itself, its only prime factor is itself. Therefore, the sum of its prime factors is simply 641.

Math question: What is the sum of the digits of the number 641 raised to the power of 2, divided by the square root of 641?

To find the sum of the digits of 641^2 / √641, we first calculate 641 raised to the power of 2, resulting in 411,281. Next, we need to find the square root of 641, which is approximately 25.317. Dividing 411,281 by 25.317 gives us an approximate value of 16,245. The sum of the digits in 16,245 equals 18 (1+6+2+4+5). Hence, the answer is 18.
