AnswersDriveInformally: When you multiply a whole number times itself, the resulting product is called a square number, or a perfect square or simply "a square." So 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
Beside this, what is the principal root?
The unique nonnegative square root of a nonnegative real number. The concept of principal square root cannot be extended to real negative numbers since the two square roots of a negative number cannot be distinguished until one of the two is defined as the imaginary unit, at which point and can then be distinguished.

How do you find the square root of 169?
To find the square root of 169, you have to find a number that can be multiplied by itself in order to get the number 169 as the product. 13 * 13 or 13^2 will give you 169. Also, when 2 negative numbers are multiplied together, you get a positive number.

What number squared is 64?
64 has two square roots, namely 8 and −8 , since:
82=(−8)2=64.
When we say "the square root", what is usually intended is "the principal square root", which in the case of the Real square root of a positive number is the positive one. Any non-zero number n has two square roots.
82=(−8)2=64.
When we say "the square root", what is usually intended is "the principal square root", which in the case of the Real square root of a positive number is the positive one. Any non-zero number n has two square roots.

Is there a perfect square for 18?
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.

What is the cube of 3?
In arithmetic and algebra, the cube of a number n is its third power: the result of the number multiplied by itself twice: n3 = n × n × n. It is also the number multiplied by its square: n3 = n × n2.

Is the number 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 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.

What is √ 144?
While -12 is "a square root" of 144, the square root operation here denotes a function from nonnegative real numbers to nonnegative real numbers. A function can only produce a single result. So the expresion evaluates to the positive root 12. 144 has two roots, yes: .
14
Is there a perfect square in 125?
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 125 is about 11.180. Thus, the square root of 125 is not an integer, and therefore 125 is not a square number.

What is a cube of a number?
A cube number is a number that is the product of three numbers which are the same. In other words, if you multiply a number by itself and then by itself again, the result is a cube number. This diagram makes this concept clearer: Cube numbers can be represented visually as 3D cubes of single, unit cubes.
