Math Question: If you divide a number by 9, add 87, multiply by 5, subtract 675, and then square the result, what is the final value of the number 1125?

To find the final value of the number 1125, let's follow the given operations step by step. First, dividing 1125 by 9 gives us 125. Then, adding 87 to 125 gives us 212. Next, we multiply 212 by 5, resulting in 1060. Subtracting 675 from 1060 gives us 385. Finally, squaring 385 yields a final value of 148225 for the number 1125. By dividing 1125 by 9, adding 87, multiplying by 5, subtracting 675, and squaring the result, we have obtained the final value of the number as 148225.

Math question: What is the sum of the prime factors of the number 1125?

To find the prime factors of 1125, we can start by dividing it by the smallest prime number, which is 2. However, 1125 is an odd number and not divisible by 2. Next, let's divide it by 3, another prime number. 1125 ÷ 3 = 375. Still an odd number, further dividing by 3 gives us 375 ÷ 3 = 125. Now we reach a prime factor, 125. Dividing 125 by itself, we get 125 ÷ 125 = 1, which is neither prime nor composite. Therefore, the prime factors of 1125 are 3 and 5. To find their sum, we add them: 3 + 5 = 8. Hence, the sum of the prime factors of 1125 is 8.

Math question: What is the smallest whole number that, when multiplied by 5, divided by 4, squared, and multiplied by 3, gives a result of 1125?

To solve this question, we can work backward. We divide 1125 by 3, giving us 375. Then, we take the square root of 375, resulting in approximately 19.3649. Since we need a whole number, we round up to 20. Now, we reverse the operations: multiplying 20 by 4 gives us 80, and then multiplying 80 by 5 gives us 400. Finally, we square 400 to obtain 160,000, which yields the desired result of 1125 when divided by 3. Thus, the answer is 20.
