To express 18,000 in scientific notation, you want to write it in the form \( a \times 10^n \), where \( 1 \leq a < 10 \).
For 18,000:
1. Move the decimal point in 18,000 four places to the left to get 1.8.
2. We moved the decimal point 4 places, so we multiply by \( 10^4 \).
Thus, 18,000 can be written as \( 1.8 \times 10^4 \).
The correct choice is:
**1.8 × 10^4**.
