To solve any equation to be radical-free, we use the formula. Numbers under the same radical and index can be multiplied, subtracted, divided, and added. How Do You Solve a Radical?Ī radical can be solved by using any of the rules mentioned above in the article. The number under the radical is called radicand and the number before the radical is called the index. is the radical should cover the entire number to conduct any of the arithmetic operations such as addition, subtraction, multiplication, or division. The horizontal bar across the number i.e. The radical or symbol means the root of any number. square root, cube root, fourth root, etc. Radical is the symbol '√' that helps in identifying the n th root of a number i.e. An inequation that is inside a radical is known as radical inequality.įAQs on Radical What is the Meaning of Radical in Math?.An expression that lies inside a square root is known as a radical expression.An equation that is inside a radical is known as a radical equation.Some examples of radicals are √7, √2y+1, etc.Ī radical can also be associated with the following terms: The number n written before the radical is called the index or degree. The horizontal line covering the number is called the vinculum and the number under it is called the radicand. The symbol '√' that expresses a root of a number is known as radical and is read as x radical n or n th root of x. This is considered to be the opposite of an exponent just like addition being the opposite of subtraction and division being the opposite of multiplication. This number helps in telling us how many times the number would be multiplied by itself to equal the radicand. The number written before the radical is known as the index number or degree. The radical can describe different kinds of roots for a number such as square root, cube root, fourth root, and so on. The term radical is derived from the Latin word Radix which means root. Thus, any number or expression that uses a root is known as a radical. The root can be a square root, cube root, or in general, n th root. The radical of a number is the same as the root of a number.
