To write 228,000 in scientific notation:

1. Move the decimal point to the left until you have a number between 1 and 10.

   • $228,000$ becomes $2.28$.

2. Count how many places you moved the decimal point:

   • The decimal was moved 5 places to the left.

Therefore, in scientific notation, $228,000$ is written as: $2.28 \times 10^5$

Does that make sense, or would you like any further clarification?
