Math Question: What is the sum of the squares of the digits in the number 3721?

To find the sum of the squares of the digits in the number 3721, we first separate the digits: 3, 7, 2, and 1. Next, we square each digit: 3^2 = 9, 7^2 = 49, 2^2 = 4, and 1^2 = 1. Now, we add the squared digits together: 9 + 49 + 4 + 1 = 63. Therefore, the sum of the squares of the digits in the number 3721 is 63.

Question: What is the square root of the difference between the product of the prime factors of 3721 and the sum of the digits of 3721, rounded to 2 decimal places?

To find the prime factors of 3721, we divide it by successive prime numbers, starting with 2. After several divisions, we find that 11 is a factor of 3721, which itself is the square of 61. Now, let's calculate the product of the prime factors: 11 * 61 = 671. Next, we sum up the digits of 3721: 3 + 7 + 2 + 1 = 13. Taking the difference between these two results: 671 - 13 = 658. Finally, finding the square root of 658 and rounding to 2 decimal places, we get approximately 25.68 as the answer.

Math question: What is the square root of 3721?

The square root of 3721 is 61. Square roots are derived by finding the number that, when multiplied by itself, gives the original number. In this case, 61 multiplied by 61 equals 3721. The concept of square roots is essential in various real-world applications, including geometry, physics, and engineering. Understanding square roots helps in solving equations, estimating distances, and working with measurements or areas of squares.
