Subtract. Write your answer in scientific notation.
(2.5×106)–(2.3×106)

To subtract the two numbers in scientific notation:

\[
(2.5 \times 10^6) - (2.3 \times 10^6)
\]

1. Since both numbers have the same power of \(10^6\), you can subtract the coefficients directly:
\[
2.5 - 2.3 = 0.2
\]

2. Now, keep the power of 10 unchanged:
\[
0.2 \times 10^6
\]

3. Express 0.2 in scientific notation:
\[
0.2 = 2.0 \times 10^{-1}
\]

4. Therefore, the result becomes:
\[
(2.0 \times 10^{-1}) \times 10^6 = 2.0 \times 10^5
\]

So, the answer in scientific notation is:

\[
2.0 \times 10^5
\]
