Math question: What is the sum of the digits when the number 8220 is multiplied by its reverse?

To find the reverse of 8220, we multiply it by 1000 (to account for the place value of each digit) and add the reverse of 8220. Thus, the reverse is 2000 + 228 (by reversing 8220) = 2228. Next, we calculate 8220 multiplied by 2228, resulting in 18,331,760. Now, summing the digits of this product, we get 1 + 8 + 3 + 3 + 1 + 7 + 6 + 0 = 29. Hence, the sum of the digits when the number 8220 is multiplied by its reverse is 29.

Math question: What is the sum of the integer divisors of the number 8220?

The number 8220 has several integer divisors, including 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 41, 60, 82, 123, 164, 205, 246, 410, 492, 615, 820, 1230, 1640, and 2460. Adding all these divisors, the sum comes out to be 11,815. Hence, the sum of the integer divisors of the number 8220 is 11,815.

Math question: What is the square root of 8220?
