A square root can also be written with an index of, but usually the 2 is understood rather than expressly written. A radical sign with an index of 3 is written as, which indicates a cube root. The principal square root is the nonnegative number that when multiplied by itself equals The square root obtained using a calculator is the principal square root. The principal square root of is written as The symbol is called a radical, the term under the symbol is called the radicand, and the entire expression is called a radical expression.
