The positive square root is also known as the principal square root, and is denoted with a radical sign:

In the expression , n is called the index, is the radical sign or radix, and x is called the radicand.

A radical equation is one that includes a radical sign, which includes square roots, , cube roots, , and nth roots, .

Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by , where is called the radical sign or radix.
