The term can be written as \sqrt[2]{-3} \hspace{3 mm}or\hspace{3 mm} -3^{1/2}.

As the index 2 is even and -3 is less than 0, -3 has two complex square roots \in \mathbb{C}:

\sqrt[2]{-3}, which is positive and called principal square root of -3, and −\sqrt[2]{-3}, which is negative.

Together, they are denominated as ±\sqrt[2]{-3}.

Although the principal negative square root of negative three is only one of the two square roots, the term “square root of -3” usually refers to the positive number.

Make sure to understand that -3 has no real square roots \in \mathbb{R}!

Next, we have a look at the inverse function.

Inverse of Square Root of -3

Extracting the square root is the inverse operation of ^2:\underbrace{ {\rm \sqrt[2]{-3} \times\thinspace ... \times\thinspace \sqrt[2]{-3}} }_{\rm 2 \thickspace times} = \sqrt[2]{-3}^{2}= -3In the following paragraph, we are going to name the elements of this √.
