Math question: What is the sum of the digits of the number obtained by multiplying the prime factors of 1142?

To find the prime factors of 1142, we divide it successively by prime numbers, starting from 2, until we can no longer divide evenly. By dividing 1142 by 2, we get 571, which is a prime number itself. Thus, the prime factors of 1142 are 2 and 571. Multiplying these factors, we obtain 2 * 571 = 1142. Now, summing the digits of this product, 1 + 1 + 4 + 2, we get 8. Therefore, the sum of the digits of the number obtained by multiplying the prime factors of 1142 is 8.

Question: What is the sum of the divisors of the number 1142, excluding 1 and itself?

To find the sum of the divisors excluding 1 and the number itself, we need to determine all the divisors of 1142. The prime factorization of 1142 is 2 × 571. To find all divisors, we combine the prime factors in different ways: (2^0) × (571^0) = 1, (2^1) × (571^0) = 2, (2^0) × (571^1) = 571, and (2^1) × (571^1) = 1142. The divisors of 1142 are 1, 2, 571, and 1142. Excluding 1 and 1142, the sum of the divisors is 2 + 571 = 573. Therefore, the sum of the divisors of the number 1142, excluding 1 and itself, is 573.

Math Question: What is the sum of 4 times the square root of 1142 added to the cube of 2 divided by the square of 3, subtracted by the difference of 40 and the remainder when 1142 is divided by 7?

To find the answer, let's break it down. First, let's compute the square root of 1142, which is approximately 33.79. Now, multiply it by 4, resulting in 135.16. Next, raise 2 to the power of 3, giving us 8. Divide that by 3 squared, which equals 9, resulting in approximately 0.89. The difference of 40 and the remainder of 1142 divided by 7 is 32. So now, subtract 32 from the previous result. Finally, add the value of 135.16 to this result, giving us a final answer of approximately 203.05.
