Math Question: How many ways can the number 2844 be rearranged such that it remains even?

To find the number of ways the number 2844 can be rearranged while keeping it even, we need to consider the unique digits it contains. Since the number contains a repetition of digit '4', we have to consider this as a single entity, rather than two separate '4's. Hence, the number of unique arrangements can be calculated using permutations. Let's denote '2' as a, '8' as b, and '4' as c. We have 4 total entities (a, b, c, c) with 2 identical 'c' digits. Using the formula for permutations with repeated elements, the number of arrangements is given by 4! / (2!) = 12. Thus, there are 12 distinct rearrangements of the digits of 2844 that keep the number even.

Math question: What is the sum of the prime factors of 2844?

To find the prime factors of 2844, we divide it by its smallest prime factor, which is 2. The result is 1422. Dividing 1422 further by 2 gives us 711, divisible by 3, resulting in 237. Again, dividing 237 by 3 gives us 79, the smallest remaining prime factor. Finally, dividing 79 by itself, we get 1. Therefore, the prime factors of 2844 are 2, 2, 3, 3, and 79. Adding these together yields the sum as 89.

Math question: If 2844 is divided by 12 and then multiplied by 9, what is the result?

To find the result, divide 2844 by 12, which equals 237, Then multiply 237 by 9, giving 2133. So, the result is 2133.
