Sum of the first 471 square numbers

We define square numbers as numbers that when squared will equal a whole number. Thus, the list of the first square numbers starts with 1, 4, 9, 16, and so on.

What is the sum of the first 471 square numbers, you ask? Here we will give you the formula to calculate the first 471 square numbers and then we will show you how to calculate the first 471 square numbers using the formula.

The formula to calculate the first n square numbers is displayed below:

		n(n + 1) × (2(n) + 1)
		6

To calculate the sum of the first 471 square numbers, we enter n = 471 into our formula to get this:

		471(471 + 1) × (2(471) + 1)
		6

First, calculate each section of the numerator: 471(471 + 1) equals 222312 and (2(471) + 1) equals 943. Therefore, the problem above becomes this:

		222312 × 943
		6

Next, we calculate 222312 times 943 which equals 209640216. Now our problem looks like this:

		209640216
		6

Finally, divide the numerator by the denominator to get our answer:

209640216 ÷ 6 = 34940036

There you go. The sum of the first 471 square numbers is 34940036.
