Sum of the first 570 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 570 square numbers, you ask? Here we will give you the formula to calculate the first 570 square numbers and then we will show you how to calculate the first 570 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 570 square numbers, we enter n = 570 into our formula to get this:

		570(570 + 1) × (2(570) + 1)
		6

First, calculate each section of the numerator: 570(570 + 1) equals 325470 and (2(570) + 1) equals 1141. Therefore, the problem above becomes this:

		325470 × 1141
		6

Next, we calculate 325470 times 1141 which equals 371361270. Now our problem looks like this:

		371361270
		6

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

371361270 ÷ 6 = 61893545

There you go. The sum of the first 570 square numbers is 61893545.
