The inverse operation of squaring nine hundred and ninety-eight is extracting the square root of 998, explained here. In the next section we elaborate on what is 998 squared, and there you can also find our calculator.

## What is 998 Squared

A square is a flat shape with four equal sides; every angle is 90°. Hence, a square with side length 998 has an area of 996004.

998 squared equals the sum of the first 998 odd numbers:

$\sum_{i=1}^{998} (2i-1)$ = 996004

In addition, the number can be calculated from 997 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
9982 = 9972 + 997 + 998 = 9972 + 1995 = 996004

It can be also be computed from 997 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
9982 = 2 x 9972 – 9962 + 2 = 2 x 994009 – 992016 + 2 = 996004

The difference between the perfect square of 998 and its predecessor, 997, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 998 – 1 = 1995 = 9982 – 9972 = 996004 – 994009 = 1995

998 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.

Squares of even numbers like 998 are divisible by 4 for $\frac{(2n)^{2}}{4}$ = n2.
