To express the number 25,600,000 in scientific notation, you can follow these steps:
1. Move the decimal point to the left until you have a number between 1 and 10. In this case, moving it 7 places to the left gives you 2.56.
2. Count how many places you moved the decimal; this will be the exponent of 10. Since we moved it 7 places, the exponent is 7.
3. Combine these parts to write the number in scientific notation.
Thus, 25,600,000 in scientific notation is:
\[
2.56 \times 10^7
\]
