## Is 24 a perfect square?

Since 102.01 is a rational number and the square root of 102.01 is a rational number (10.1), 102.01 is a perfect square.

24 is NOT a perfect square.

24 is a natural number, but since there is no other natural number that can be squared to result in the number 24, 24 is NOT a perfect square..

## IS 242 a perfect square?

The square root of 242 in exact form is 11√(2). Though 242 is not a perfect square, it does have a perfect square as a factor (namely 121).

## What is considered a perfect square?

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.

## Does square root give two answers?

It has multiple answers so why do we pick the positive one? if x2=16⟹x=√16 or x=−√16 for respectively the positive and negative solution. This implies that the square root function has a single answer and we must negate its answer to obtain the second solution.

## Is 18 a perfect square?

Is 18 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 18 is about 4.243. Thus, the square root of 18 is not an integer, and therefore 18 is not a square number.

## Why is i the square root of negative one?

Here, the term “imaginary” is used, because there is no real number having a negative square. There are two complex square roots of −1, namely +i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).

## What are the factors of 249?
