## Is 522 a perfect square number?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 522 is about 22.847.

Thus, the square root of 522 is not an integer, and therefore 522 is not a square number.

## What is the square number of 522?

The square of a number (here 522) is the result of the product of this number (522) by itself (i.e., 522 × 522); the square of 522 is sometimes called "raising 522 to the power 2", or "522 squared".

The square of 522 is 272 484 because 522 × 522 = 5222 = 272 484.

As a consequence, 522 is the square root of 272 484.

## Number of digits of 522

522 is a number with 3 digits.

## What are the multiples of 522?

The multiples of 522 are all integers evenly divisible by 522, that is all numbers such that the remainder of the division by 522 is zero. There are infinitely many multiples of 522. The smallest multiples of 522 are:

## How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 522). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 22.847). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
