### What number is a perfect square?

Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1,

**4**,**9**,**16**,**25**,**36**,**49**,**64**,**81**,**100**… Here are the square roots of all the perfect squares from 1 to**100**.#### Is the number 36 a perfect square?

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**36 is**6. Therefore, the**square**root of**36 is**an integer, and as a consequence**36 is**a**perfect square**.#### What is √ 9?

In mathematics, a**square root**of a number a is a number y such that y^{2}= a; in other words, a number y whose square (the result of multiplying the number by itself, or y⋅y) is a. For example, the principal**square root**of**9**is 3, which is denoted by**√9**= 3, because 3^{2}= 3. • 3 =**9**and 3 is nonnegative.#### Is the number 48 a perfect square?

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**48**is about 6.928. Thus, the**square**root of**48**is not an integer, and therefore**48**is not a**square**number.

### Is there a perfect square in 30?

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**30**is about 5.477. Thus, the**square**root of**30**is not an integer, and therefore**30**is not a**square**number.#### What are all the factors of 9?
