To subtract the numbers in scientific notation, we first align them properly with the same power of ten:
\[
(4.9 \times 10^8) - (2.39 \times 10^8) = (4.9 - 2.39) \times 10^8
\]
Next, we perform the subtraction on the coefficients:
\[
4.9 - 2.39 = 2.51
\]
Now we can express the result in scientific notation:
\[
2.51 \times 10^8
\]
So, the final answer is:
\[
\boxed{2.51 \times 10^8}
\]
\[
(4.9 \times 10^8) - (2.39 \times 10^8) = (4.9 - 2.39) \times 10^8
\]
Next, we perform the subtraction on the coefficients:
\[
4.9 - 2.39 = 2.51
\]
Now we can express the result in scientific notation:
\[
2.51 \times 10^8
\]
So, the final answer is:
\[
\boxed{2.51 \times 10^8}
\]
