The square root is a very important concept in many areas of science. A number $r$ is said to be a square root of a given number if the given number $=r^2.$ It is denoted by the radical symbol $\sqrt{}.$ So we have \[r=\sqrt{r^2}.\] For example, we know that $2 \times 2=4,$ so by definition the square root of $4$ is $2.$
