Math question: What is the sum of all even digits in the number 7197?

To find the sum of even digits, we need to consider the individual digits in the number. The number 7197 has only one even digit, which is 7. Since there are no other even digits, the sum would be 7.

Math Question: Given the number 7197, what is the sum of its digits when multiplied by 3, divided by its difference with 1000, and subtracted by its square root, rounded to the nearest whole number?

To solve the question, we first calculate the sum of digits: 7 + 1 + 9 + 7 = 24. Multiplying this by 3 gives us 72. Next, we find the difference between 7197 and 1000, which is 6197. Dividing 72 by 6197 yields approximately 0.0116122721. Finally, the square root of 7197 is approximately 84.936. Therefore, subtracting the square root from 0.0116122721 results in -84.9243877278. When rounded to the nearest whole number, the answer is -85.

Question: What is the sum of the digits of the square root of the number 7197?

To find the square root of 7197, we first determine the two closest perfect squares: 81 (9^2) and 100 (10^2). Since 81 is smaller, we know the square root of 7197 will be between 90 and 100. By approximation, let's assume the square root of 7197 lies between 94 and 95. Squaring 94, we get 8836, and squaring 95, we get 9025. Since 7197 falls in between these two values, we can interpolate to estimate the square root. The difference between 9025 and 8836 is 189. The difference between 7197 and 8836 is 1639. Using proportions, we find that the digit difference between the two squared results corresponds to adding approximately 6.14 to the estimated square root of 94. Thus, the square root of 7197 is estimated to be around 94.14. Summing the digits of 94 and 14, we obtain 9 + 4 + 1 + 4 = 18. Therefore, the sum of the digits of the square root of 7197 is 18.
