The problem asks for an estimate of the number \( 425,230 \) in scientific notation.

To convert a number into scientific notation:
1. Move the decimal point until there's one non-zero digit to the left.
2. Multiply by \( 10 \) raised to the number of places you moved the decimal.

For \( 425,230 \), we move the decimal point 5 places to the left, making the number \( 4.2523 \times 10^5 \). Since this is an estimate, we round \( 4.2523 \) to 4, giving \( 4 \times 10^5 \).

The correct answer is **\( 4 \times 10^5 \)**, as selected in the image.
