The square root is the inverse operation to a power with exponent 2.

√81 = 9, because 9^{2} = 81

The terms of the square root √a = b are the **radicand a**, and the **root b**.

There are several types of square roots:

1. **Exact square root**. An exact square root has the remainder 0.

√Radicand = (Exact root)^{2}

√36 = 6 36 = 6^{2}

The result of an **exact square root** is a **perfect square**. The numbers that have **exact square roots** are **1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, ...**

2. **Not exact square root**. If a number is not a perfect square, the square root is no exact, so there is a remainder.

√Radicand = (Root)^{2} + Remainder

√23 = 4^{2} + 7
