Math question: What is the largest number that is a multiple of 3, a multiple of 7, and divisible by 11?

To find the largest number satisfying these conditions, we need to find the least common multiple (LCM) of 3, 7, and 11. The LCM of 3 and 7 is 21, and the LCM of 21 and 11 is 231. Now, let's find the largest multiple of 231 that is less than or equal to 249. We divide 249 by 231 and get a quotient of 1 with a remainder of 18. Therefore, we can fit 231 once in 249. Thus, the largest number that is a multiple of 3, a multiple of 7, and divisible by 11, which is less than or equal to 249, is 231.

Math question: What is the sum of 249 and twice the square root of 249 minus the square of the cube root of 249?

To find this, we first calculate the square root of 249, which is approximately 15.8114. The cube root of 249 is roughly 6.2885. Now, we square the cube root: 6.2885 squared is approximately 39.6322. Next, we multiply the square root by 2 and obtain 31.6228. Finally, we add 249 to 31.6228 and subtract 39.6322 to get the answer: 240.9906. Therefore, the sum of 249, twice the square root of 249, and minus the square of the cube root of 249 is roughly 240.9906.

Math question: What is the smallest multiple of 249 that can be expressed as the sum of two squares?

To find the smallest multiple of 249 that can be expressed as the sum of two squares, we need to consider the prime factorization of 249. It can be written as 3 * 83, where both of these factors are prime. Now, to express a number as the sum of two squares, it must not contain any prime factors of the form 4k+3 raised to an odd power. In the prime factorization of 249, we have 83, which is of the form 4k+3. Thus, to obtain the smallest multiple of 249 that can be expressed as the sum of two squares, we need to remove the factor 83. The remaining factor, which is 3, can be expressed as the sum of two squares (3 = 1^2 + 1^2). Hence, the answer is 249 * 1^2 + 249 * 1^2 = 249 + 249 = 498. Therefore, the smallest multiple of 249 that can be expressed as the sum of two squares is 498.
