To write 523,000 in scientific notation, follow these steps:

1. Move the decimal point: Start by writing 523,000 as $5.23$ (move the decimal point 5 places to the left).

2. Count the number of places the decimal moved: Since the decimal moved 5 places, this gives you the exponent for the power of 10.

3. Write it in scientific notation: Combine the new number $5.23$ with the exponent $10^5$.

Thus, 523,000 in scientific notation is: $5.23 \times 10^5$
