9972 = 994009
997 x 997 = 994009

The inverse operation of squaring nine hundred and ninety-seven is extracting the square root of 997, explained here. In the next section we elaborate on what is 997 squared, and there you can also find our calculator.

## What is 997 Squared

A square is a flat shape with four equal sides; every angle is 90°. Hence, a square with side length 997 has an area of 994009.

997 squared equals the sum of the first 997 odd numbers:

$\sum_{i=1}^{997} (2i-1)$ = 994009

In addition, the number can be calculated from 996 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
9972 = 9962 + 996 + 997 = 9962 + 1993 = 994009

It can be also be computed from 996 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
9972 = 2 x 9962 – 9952 + 2 = 2 x 992016 – 990025 + 2 = 994009

The difference between the perfect square of 997 and its predecessor, 996, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 997 – 1 = 1993 = 9972 – 9962 = 994009 – 992016 = 1993

997 is odd, and the square numbers of odd numbers are also odd: (2n + 1)2 = 4 × (n2 + n) + 1.

Squares of odd numbers like 997 are of the form 8n + 1, because (2n + 1)2 = 4n × (n + 1) + 1;
n × (n + 1) is an even number.
