The expression shown in the image is:

\[
4 \sqrt{5} - 7
\]

This represents:

1. The square root of 5, which is \( \sqrt{5} \approx 2.236 \).
2. Multiply that by 4, giving \( 4 \times 2.236 = 8.944 \).
3. Finally, subtract 7 from the result: 
   \[
   8.944 - 7 = 1.944
   \]

So, the simplified result is approximately **1.944**.
