# 7 Squared

7 squared, (7)2, is the number you get when multiplying 7 times 7.

It can also be looked at as exponentiation involving the base 7 and the exponent 2.

The term is usually pronounced seven times seven or seven squared.

The square of 7 is a perfect square because the number is the product of the two equal integers 7.

It can be written as 7 × 7 or in exponential form.

The inverse operation of squaring seven is extracting the square root of 7, explained here.

In the next section we elaborate on what is 7 squared and there you can also find our calculator.

## What is 7 Squared?

A square is a flat shape with four equal sides; every angle is 90°.

Hence, a square with side length 7 has an area of 49.

7 squared equals the sum of the first 7 odd numbers:

In addition, the number can be calculated from 6 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(7)2 = 62 + 6 + 7 = 62 + 13 = 49

It can be also be computed from 6 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(7)2 = 2 x 62 – 52 + 2 = 2 x 36 – 25 + 2 = 49

The difference between the perfect square of 7 and its predecessor, 6, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 7 – 1 = 13 = (7)2 – 62 = 49 – 36 = 13

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

Squares of odd numbers like 7 are of the form 8n + 1, because (2n + 1)2 = 4n × (n + 1) + 1;
n × (n + 1) is an even number.
