The expression in the image is:

\[
4 - 3\sqrt{-1}
\]

Here, \(\sqrt{-1}\) represents the imaginary unit, often denoted by \(i\), where \(i = \sqrt{-1}\). Substituting \(i\) for \(\sqrt{-1}\), we can rewrite the expression as:

\[
4 - 3i
\]

This expression is in the form of a complex number, where \(4\) is the real part, and \(-3i\) is the imaginary part.

**Final Answer:**  
The simplified form of the expression is:

\[
4 - 3i
\]
