In math, the radical symbol is used to represent taking the square root of an expression. Typically the radical symbol is used in an expression like this: In plain language, this means “take the square root of the number four”. The graph of the function f(x) = √x, made up of half a parabola with a vertical directrix The principal square root function (usually just referred to as the "square root function") is a function that maps the set of nonnegative real numbers onto itself. The √ symbol, universally

recognized as the "Square Root", is one of the fundamental symbols in mathematics, representing the operation to find a number that, when multiplied by itself, yields the given number. But wait a minute! Can't the square root also be −5? Because (−5) × (−5) = 25 too. Well the square root of 25 could be −5 or +5. But with the radical symbol √ we only give the positive (or zero) result. Here, ‘√’ is the radical symbol used to represent the root of numbers. The positive number, when multiplied by itself, represents the square of the number. The radical symbol (√), also known as the square root symbol, is one of the most fundamental mathematical operators. Introduced in 1525 by German mathematician Christoff Rudolff, it has become the universal symbol for representing square roots in mathematics, science, and engineering worldwide. Our square root calculator estimates the square root of any positive number you want. Just enter the chosen number and read the results. Everything is calculated quickly and automatically! To calculate √ a: Divide a by b. If the number c returned is precise to the desired decimal place, stop. Calculating nth roots can be done using a similar method, with modifications to deal with n. While computing square roots entirely by hand is tedious. Jul 23, 2025 · Square root of a number is essentially the value that, when multiplied by itself, yields the original number. This concept is denoted by the radical symbol (√) and is expressed as √n or n1/2, where 'n' is a positive number. For example, if you have the number 25 then the square root is 5 because 5*5 is 25, or 25 divided by 5 is 5. Each positive real number has two square roots, one positive and the other negative. The radical symbol refers to the principal value of the square root function called the principal square root, which is the positive one.
