Question: Find the square of a number such that when 538 is added to it, the result is 18,342.

Let the number be x. We have the equation x^2 + 538 = 18,342. Rearranging, we get x^2 = 17,804. Taking the square root of both sides, x ≈ √(17,804) ≈ 133.74 (rounded to two decimal places). Thus, the square root of the number which, when squared and added to 538, results in 18,342 is approximately 133.74.

Math question: What is the sum of the prime factors of 538?

To find the prime factors of 538, we need to factorize it first. By dividing it successively, we get: 538 ÷ 2 = 269. Since 269 is a prime number, the prime factorization of 538 is 2 × 269. Now, to find the sum of the prime factors, we add them: 2 + 269 = 271. Therefore, the sum of the prime factors of 538 is 271.

Math Question: The number 538 is divided by 7. What is the remainder?

To find the remainder when 538 is divided by 7, we perform the division: Since 7 does not divide evenly into the first digit (5), we carry it over to the next digit, creating the number 53. Now, we divide 53 by 7, which gives us a quotient of 7 and a remainder of 4. Thus, the remainder when 538 is divided by 7 is 4.
