30 Squared

30 squared, (30)2, is the number you get when multiplying 30 times 30.

It can also be looked at as exponentiation involving the base 30 and the exponent 2.

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

The square of 30 is a perfect square because the number is the product of the two equal integers 30.

It can be written as 30 × 30 or in exponential form.

The inverse operation of squaring thirty is extracting the square root of 30, explained here.

In the next section we elaborate on what is 30 squared and there you can also find our calculator.

What is 30 Squared?

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

Hence, a square with side length 30 has an area of 900.

30 squared equals the sum of the first 30 odd numbers:


In addition, the number can be calculated from 29 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(30)2 = 292 + 29 + 30 = 292 + 59 = 900

It can be also be computed from 29 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(30)2 = 2 x 292 – 282 + 2 = 2 x 841 – 784 + 2 = 900

The difference between the perfect square of 30 and its predecessor, 29, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 30 – 1 = 59 = (30)2 – 292 = 900 – 841 = 59

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

Squares of even numbers like 30 are divisible by 4 for


= n2.
