Math question: What is the square root of the sum of 2789 and its reverse?

To find the square root of the sum of 2789 and its reverse, we first need to calculate the reverse of 2789. Reversing 2789 gives us 9872. Adding 2789 and its reverse, we get 2789 + 9872 = 12661. Finally, taking the square root of 12661, we find that the answer is approximately 112.486.

Math question: What is the greatest common divisor (GCD) of 2789 and the sum of its digits?

To find the GCD of 2789 and the sum of its digits, we first find the sum: 2 + 7 + 8 + 9 = 26. Then, we calculate the GCD using the Euclidean algorithm. Taking the larger number as 2789 and the smaller as 26, the remainder when 2789 is divided by 26 is 25. Next, we divide 26 by 25, which gives a remainder of 1. Continuing the process, we divide 25 by 1, resulting in no remainder. Thus, the GCD of 2789 and 26 is 1. Therefore, the answer is that the greatest common divisor of 2789 and the sum of its digits (26) is 1.

What is the sum of the digits of the number 2789, when each digit is raised to the power of its respective place value and added together? (e.g. 2^3 + 7^2 + 8^1 + 9^0)

When we evaluate each digit, we get 2^3 + 7^2 + 8^1 + 9^0 = 8 + 49 + 8 + 1 = 66. Therefore, the sum of the digits of the number 2789 is 66.
