To add \(5.3 \times 10^5\) and \(3.8 \times 10^4\), we first need to express both numbers in terms of the same power of ten.
We can convert \(3.8 \times 10^4\) to the same power of ten as \(5.3 \times 10^5\):
\[
3.8 \times 10^4 = 0.38 \times 10^5
\]
Now, we can add:
\[
5.3 \times 10^5 + 0.38 \times 10^5 = (5.3 + 0.38) \times 10^5 = 5.68 \times 10^5
\]
Thus, the sum of \(5.3 \times 10^5\) and \(3.8 \times 10^4\) in scientific notation is:
\[
\boxed{5.68 \times 10^5}
\]
