In mathematics, radical signs are, #sqrt# , # root3# , #root4#..... When any number appears under these signs, the expression as a whole is called a radical

Explanation:

In mathematics, radical signs are, like #sqrt# , # root3# , #root4#..... When any number appears under these signs, that is called a radicand and the expression as a whole is called a radical. This is what the radical form means. These are all irrational numbers, which means they cannot be expressed as a fraction in the form #p/q# where p and q are integers.
