**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?

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:

n

^{2}= (n − 1)

^{2}+ (n − 1) + n = (n − 1)

^{2}+ (2n − 1)

(7)

^{2}= 6

^{2}+ 6 + 7 = 6

^{2}+ 13 = 49

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

n

^{2}= 2 x (n − 1)

^{2}− (n − 2)

^{2}+ 2

(7)

^{2}= 2 x 6

^{2}– 5

^{2}+ 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 n

^{2}− (n − 1)

^{2}= 2n − 1:

2 x 7 – 1 = 13 = (7)

^{2}– 6

^{2}= 49 – 36 = 13

7 is odd, and the square numbers of odd numbers are also odd: (2n + 1)

^{2}= 4 × (n

^{2}+ 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.
