To subtract the numbers \(5.6 \times 10^2\) and \(1.91 \times 10^2\), we first ensure they are expressed in a compatible format with the same power of 10.
Both numbers are already in terms of \(10^2\):
\[
5.6 \times 10^2 - 1.91 \times 10^2
\]
This can be factored out as:
\[
(5.6 - 1.91) \times 10^2
\]
Now, we perform the subtraction:
\[
5.6 - 1.91 = 3.69
\]
Thus, we have:
\[
(3.69) \times 10^2
\]
Finally, we write the result in scientific notation:
\[
3.69 \times 10^2
\]
So the final answer is:
\[
\boxed{3.69 \times 10^2}
\]
