In general terms, if a is a positive real number, then the square root of a is a number that, when multiplied by itself, gives a. The square root could be positive or negative because multiplying two negative numbers gives a positive number. The principal square root is the nonnegative number that when multiplied by itself equals a. The square root obtained using a calculator is the principal square root. — The principal square root of a is written as √ a . The symbol is called a radical, the term under the symbol is called the radicand, and the entire expression is called a radical expression.
