Question: What is the sum of the prime factors of the perfect square closest to 771?

To find the perfect square closest to 771, we calculate the square root of 771 to be approximately 27.77. The nearest perfect square is 784 (28^2 = 784). Now, we need to find the prime factors of 784 which are 2 and 7. Adding these prime factors gives us 2 + 7 = 9. Therefore, the sum of the prime factors of the perfect square closest to 771 is 9.

Question: What is the sum of the distinct prime factors of the square root of the sum of digits in the number 771?

To find the square root of 771, we get approximately 27.787 (rounded to three decimal places). The sum of the digits in 771 is 7 + 7 + 1 = 15. Taking the square root of 15 gives approximately 3.873 (rounded to three decimal places). The prime factors of 3.873 are 3 and 17. Therefore, the distinct prime factors of the square root of the sum of digits in 771 are 3 and 17. The sum of these prime factors is 3 + 17 = 20. Hence, the answer is 20.

Math question: If a number is multiplied by 8 and then added to 135 to obtain the result 771, what is the number?

Let's assume the number is represented by x. According to the question, the equation becomes 8x + 135 = 771. By subtracting 135 from both sides, we have 8x = 636. Now, dividing both sides by 8, we find x = 79.5. Therefore, the number is 79.5. In this question, we used basic algebra to find the value of the unknown number. We first isolated the variable x by subtracting 135 from both sides of the equation. Then, to solve for x, we divided both sides by 8. Thus, by simplifying the equation, we calculated that the number is 79.5.
