What is the square root of a number?

The square root of a number is the inverse operation of the square of that number. That means:

\boxed{square (n) = n^2}
\boxed{square root (n^2) = n}

For example:

\boxed{square(7) = 7^2 = 49}
\boxed{square root(49) = \sqrt{49} = 7}

Then, the square root of a number is a value, that, multiplied by itself, gives the number.
