To subtract the numbers \( (8.97 \times 10^2) - (5 \times 10^2) \), we can factor out the common \( 10^2 \):
\[
(8.97 - 5) \times 10^2
\]
Now perform the subtraction inside the parentheses:
\[
8.97 - 5 = 3.97
\]
Now, substitute that back into the expression:
\[
3.97 \times 10^2
\]
This is already in scientific notation, as the coefficient (3.97) is between 1 and 10. Therefore, the final answer is:
\[
\boxed{3.97 \times 10^2}
\]
