It can also be looked at as exponentiation involving the base 8 and the exponent 2.
The term is usually pronounced eight times eight or eight squared.
The square of 8 is a perfect square because the number is the product of the two equal integers 8.
It can be written as 8 × 8 or in exponential form.
Read on to learn everything about the number eight squared, including useful identities.
8 × 8 = 64
The inverse operation of squaring eight is extracting the square root of 8, explained here.
In the next section we elaborate on what is 8 squared and there you can also find our calculator.
What is 8 Squared?A square is a flat shape with four equal sides; every angle is 90°.
Hence, a square with side length 8 has an area of 64.
8 squared equals the sum of the first 8 odd numbers:
In addition, the number can be calculated from 7 squared using the following identity:
n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(8)2 = 72 + 7 + 8 = 72 + 15 = 64
It can be also be computed from 7 squared with this identity:
n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(8)2 = 2 x 72 – 62 + 2 = 2 x 49 – 36 + 2 = 64
The difference between the perfect square of 8 and its predecessor, 7, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:
2 x 8 – 1 = 15 = (8)2 – 72 = 64 – 49 = 15
8 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.
Squares of even numbers like 8 are divisible by 4 for
