2. The square root, also known as the quadratic root, is expressed as [√ ̄], in which the square root belonging to a non-negative number is called the arithmetic square root.

3. A positive number has two real square roots, which are opposite to each other; 0 has only one square root, which is 0 itself; Negative numbers have two conjugate pure imaginary square roots.
