What is the sum of the digits of the number 6961 when each digit is squared, divided by the number of prime factors it has, and multiplied by the square root of the number itself, rounded to the nearest whole number?

To solve the question, first, find the sum of the squares of the digits: 6^2 + 9^2 + 6^2 + 1^2 = 36 + 81 + 36 + 1 = 154. The number 6961 has two prime factors: 7 and 17. Now, divide the sum by the number of prime factors: 154 ÷ 2 = 77. The square root of 6961 is approximately 83.4350288425; rounding to the nearest whole number yields 83. Finally, multiply the result by the square root: 77 × 83 = 6,391. Therefore, the answer is 6,391.

Math question: Find the sum of the digits in the number 6961.

To find the sum of the digits, we break down the number 6961. The digit 6 appears once, the digit 9 appears once, and the digit 1 appears twice. Adding these digits together, we have 6 + 9 + 1 + 1 = 17. Therefore, the sum of the digits in the number 6961 is 17.

Math question: What is the closest square number to 6961?

The closest square number to 6961 is 6936. We can determine this by finding the square root of 6961, which is approximately 83.48. Rounding down to the nearest whole number gives us 83. Then, squaring 83 results in 6889, which is less than 6961. However, if we square 84, we get 7056 which is greater than 6961. Hence, 6936 is the closest square number to 6961.
