0.00000805
805,000
8,050,000

Answer 1

To convert \( 8.05 \times 10^{-5} \) into standard notation, you move the decimal point 5 places to the left (because of the negative exponent).

Starting with 8.05:
1. Move the decimal point 1 place left: 0.805
2. Move the decimal point 2 places left: 0.0805
3. Move the decimal point 3 places left: 0.00805
4. Move the decimal point 4 places left: 0.000805
5. Move the decimal point 5 places left: 0.0000805

So, \( 8.05 \times 10^{-5} \) is equal to \( 0.0000805 \).

The correct answer is:

**0.0000805**
