To convert \( 4.6 \times 10^{-4} \) to standard form, you move the decimal point in the number \( 4.6 \) four places to the left (because of the negative exponent).
Starting with \( 4.6 \):
- Move the decimal point one place to the left: \( 0.46 \)
- Move it a second place: \( 0.046 \)
- Move it a third place: \( 0.0046 \)
- Move it a fourth place: \( 0.00046 \)
So, \( 4.6 \times 10^{-4} \) in standard form is \( 0.00046 \).
