To simplify the expression \( 28 - \sqrt{38} \), we first identify that \( 28 \) is a whole number and \( \sqrt{38} \) is an irrational number, approximately equal to \( 6.16 \).
The expression cannot be simplified further in terms of elementary operations involving integers or simple radicals because they do not combine. Hence, we can rewrite it as:
\[
28 - \sqrt{38}
\]
If you need a numerical approximation, you can calculate:
\[
28 - \sqrt{38} \approx 28 - 6.16 \approx 21.84
\]
So, the simplified expression remains:
\[
28 - \sqrt{38} \quad (\text{exact form})\quad \approx 21.84 \quad (\text{numerical approximation})
\]
