The Square Root Symbol. This is the special symbol that means "square root", it is like a tick, and actually started hundreds of years ago as a dot with a flick upwards. It is called the radical, and always makes mathematics look important! We can use it like this: and we say "square root of 9 equals 3".

Definition and Notation. The square root of a number a a, denoted \sqrt {a} a, is the number b b such that. b^ {2} = a\text { and }b\ge 0. b2 = a and b ≥ 0. The square root symbol " \sqrt {\ } " is also sometimes called a radical. The number or expression underneath the top line of the square root symbol is called the radicand.
Definition. Here is the definition: A square root of x is a number r whose square is x: r 2 = x. The Square Root Symbol. This is the special symbol that means "square root", it is like a tick, and actually started hundreds of years ago as a dot with a flick upwards. It is called the radical, and always makes mathematics look important!
The square root of a number is the factor that we can multiply by itself to get that number. The symbol for square root is 1 . Finding the square root of a number is the opposite of squaring a number. Example: 4 × 4 or 4 2 = 16. So 16 = 4. If the square root is a whole number, it is called a perfect square!
The square root formula is used to find the square root of a number. We know the exponent formula: n√x x n = x 1/n. When n = 2, we call it square root. We can use any of the above methods for finding the square root, such as prime factorization, and so on. 9 1/2 = √9 = √ (3×3) = 3.
Square root. A square root is a number that can be multiplied by itself to give us the value under the radical symbol (also referred to as the radix). A square root is denoted as follows: In the figure above, z is the square root of x. We can also write this as "z raised to the power of 2 is equal to x" as follows: z 2 = x.
