Math Question: Consider the number 1557, which is expressed as the product of two distinct prime numbers. The sum of these prime factors, when multiplied by their difference, equals 679. Find the two prime factors.

Let's assume the prime factors as x and y. From the given information, we set up the equations: (x + y) * (x - y) = 679 and x * y = 1557. Solving these equations simultaneously, we find x = 69 and y = 23. Therefore, the two prime factors of 1557 are 23 and 69, and their sum multiplied by their difference does indeed equal 679.

Math question: If 30% of a number is equal to 467, what is the number?

To find the number, we can use the equation: 0.3x = 467. Solving for x: x = 467 / 0.3 ≈ 1557.333. Therefore, the number is approximately 1557.

Question: What is the sum of the digits of the number 1557 when raised to the power of 3, subtracted from the square root of the number itself, squared, multiplied by 10, and divided by the sum of the number and the square root of 1557?

To solve this, let's break it down step by step. First, calculating the sum of the digits of 1557, we have 1 + 5 + 5 + 7 = 18. Now, raising 1557 to the power of 3, we get 3,836,821,593. Taking the square root of 1557, which is approximately 39.457, squaring it gives us approximately 1,556.535. Multiplying this by 10 yields 15,565.35. To find the sum of the digits when raised to the power of 3, subtracted from the squared square root, multiplied by 10, and divided by the sum of the number and the square root, we have: (15,565.35 - 3,836,821,593) / (1557 + 39.457) = -3,836,805,028.957 / 1596.457 ≈ -2,401,706.917 Hence, the result is approximately -2,401,706.917.
