Question: What is the sum of the first 10 even numbers greater than 780?

To find the sum of the first 10 even numbers greater than 780, we can start with 782 and keep adding the next even numbers. The ten even numbers greater than 780 are 782, 784, 786, 788, 790, 792, 794, 796, 798, and 800. Adding these numbers together, we get 782 + 784 + 786 + 788 + 790 + 792 + 794 + 796 + 798 + 800 = 7890. Therefore, the sum of the first 10 even numbers greater than 780 is 7890.

Math question: What is the value of 780 divided by 2, multiplied by 10, and subtracted by 20?

To find the answer, first divide 780 by 2, which gives 390. Then multiply 390 by 10, resulting in 3900. Finally, subtract 20 from 3900, yielding 3880 as the answer. Therefore, the value of the expression is 3880.

Math question: The number 780 can be expressed as the product of two distinct prime numbers. What are these two prime numbers?

To find the prime factors of 780, we divide the number by the smallest prime number, which is 2. So, 780 divided by 2 gives us 390. Next, we divide 390 by the prime number 2 again and get 195. Continuing this process, we divide 195 by the prime number 3, and it leaves us with 65. Dividing 65 by the prime number 5, we find it equals 13, which is a prime number. Hence, we conclude that the prime factors of 780 are 2, 2, 3, 5, and 13.
