Sum of the first 4970 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 4970 square numbers, you ask? Here we will give you the formula to calculate the first 4970 square numbers and then we will show you how to calculate the first 4970 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 4970 square numbers, we enter n = 4970 into our formula to get this:

		4970(4970 + 1) × (2(4970) + 1)
		6

First, calculate each section of the numerator: 4970(4970 + 1) equals 24705870 and (2(4970) + 1) equals 9941. Therefore, the problem above becomes this:

		24705870 × 9941
		6

Next, we calculate 24705870 times 9941 which equals 245601053670. Now our problem looks like this:

		245601053670
		6

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

245601053670 ÷ 6 = 40933508945

There you go. The sum of the first 4970 square numbers is 40933508945.
