Roots, often written as radicals, identify the quantity that must be raised to a specific exponent to produce a given value. A radical expression consists of two main components: the radicand, which is the value placed inside the root symbol, and the index, which indicates the degree of the root being taken.

If no index is shown, it is considered 2 and called the square root. An index of 3 is the cube root. Higher indices are the fourth root, fifth root, and so on.
