Math question: What is the sum of the prime factors of the even number obtained by subtracting the square root of 909 from the cube root of 909?

To find the sum of the prime factors, we first determine the even number by subtracting √909 from ∛909. √909 ≈ 30.1508 and ∛909 ≈ 9.5349. Subtracting these values, we get 9.5349 - 30.1508 ≈ -20.6159, which is an even number due to the subtraction of two irrational numbers. The prime factors of -20.6159 are -1, 2, and 10307. Adding these prime factors, we obtain -1 + 2 + 10307 = 10308. Therefore, the sum of the prime factors of the even number obtained from √909 - ∛909 is 10308.

Math question: What is the largest number that divides 909 evenly without leaving a remainder, that is not itself or 1?

To find the largest number that divides 909 evenly, we can begin checking divisibility by prime numbers greater than 1. Firstly, divide by 2, but it does not divide 909. Next, divide by 3, and amazingly, it divides evenly. 909 ÷ 3 = 303. Now, let's check if any prime number greater than 3 divides 303. Dividing by 5 gives 303 ÷ 5 = 60.6, which does not result in a whole number. Performing the same process for primes 7, 11, 13, 17, 19, 23, 29, 31, and so on, none will divide evenly. Therefore, the largest number that divides 909 evenly, other than 909 itself or 1, is 3.

Math question: If you divide a number by 3, add 7 to the quotient, and then multiply the sum by 10, the result is 909. What is the original number?

Let's represent the original number as x. We can set up the equation: (x/3 + 7) * 10 = 909. To solve for x, first distribute the 10: (x/3) * 10 + 7 * 10 = 909. Simplifying further yields 10x/3 + 70 = 909. Subtracting 70 from both sides, we get 10x/3 = 839. Multiply both sides by 3/10 to isolate x: (10x/3) * (3/10) = 839 * (3/10). The threes cancel out, leaving us with x = 2517/10 = 251.7. Therefore, the original number is 251.
