The number \( 3.07 \times 10^{-4} \) in standard decimal form is calculated by moving the decimal point four places to the left (because of the negative exponent).
Starting with \( 3.07 \):
- Move the decimal four places to the left: \( 3.07 \) becomes \( 0.000307 \).
Therefore, \( 3.07 \times 10^{-4} \) written in standard form is \( 0.000307 \).
So the correct answer is \( 0.000307 \).
