The radical symbol, also known as the square root symbol, is used in math to represent the square root operator and to represent taking the nth-root of an expression.
In mathematics, the radical symbol, radical sign, root symbol, radix, or surd is a symbol for the square root or higher-order root of a number. The square root of a number x is written as , while the n th root of x is written as .
These are represented similarly, but with a small numeral above the radical symbol indicating the degree of the root. For instance, the cube root of 8 is written as \( \sqrt[3]{8} \) and equals 2, as \(2 \times 2 \times 2 = 8\).
Every nonnegative real number x has a unique nonnegative square root, called the principal square root or simply the square root (with a definite article, see below), which is denoted by , where the symbol " " is called the radical sign [2] or radix.
What is the Radical Symbol? The Radical Symbol is used to indicate the square root or n-th root of a number. It comes in various forms like √ for square root, ∛ for cube root, and ∜ for fourth root.
The number or expression written under a root symbol or radical sign is known as radicand in math. Click to know more about radicand, radical, and index in math along with solved examples and practice questions.
The square root symbol in words is said to be a ‘radical’. Or we can say a radical symbol (√ ) is used to represent the square root of any natural number. Square root formula: The formula to find the square root is: y = √a. Or. y 2 = a. Basically we use the prime factorisation method to find the square root of any number. Example: 100 ...
