Answer 1

Answer:

What is the sum of the first 1273 square numbers, you ask? Here we will give you the formula to calculate the first 1273 square numbers and then we will show you how to calculate the first 1273 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 1273 square numbers, we enter n = 1273 into our formula to get this:

1273(1273 + 1) × (2(1273) + 1)

6

First, calculate each section of the numerator: 1273(1273 + 1) equals 1621802 and (2(1273) + 1) equals 2547. Therefore, the problem above becomes this:

1621802 × 2547

6

Next, we calculate 1621802 times 2547 which equals 4130729694. Now our problem looks like this:

4130729694

6

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

4130729694 ÷ 6 = 688454949

There you go. The sum of the first 1273 square numbers is 688454949.
