Square Root In ^{m}Öa, m is the index or order, Ö is the radical or square root sign and a is the radicand. a*a = a^{2} and (a)*(a) = a^{2}. Here 'a' is called the square root of a^{2}. Thus for a &a are two square roots of a^{2}. We denote square root with the symbol ' Ö '.
Example : What is the value of Ö25 ?
Directions: Answer the following questions. Also write at least five more examples of your own for each root (first, second, and third root).
