![]() In mathematics, the traditional operations on numbers are addition, subtraction, multiplication, and division. Thus, the word radical doesn't mean far-reaching or extreme, but instead foundational, reaching the root cause. ![]() x is called a root or radical because it is the hidden base of a. The last question is, why is the square root operation called root regardless of its true origin? The explanation should become more evident if we write the equation x = ⁿ√a in a different form: xⁿ = a. The notation of the higher degrees of a root has been suggested by Albert Girard, who placed the degree index within the opening of the radical sign, e.g., ³√ or ⁴√. ![]() Although the radical symbol with vinculum is now in everyday use, we usually omit this overline in many texts, like in articles on the internet. The "bar" is known as a vinculum in Latin, meaning bond. The first use of the square root symbol √ didn't include the horizontal "bar" over the numbers inside the square root (or radical) symbol, √‾.
