To write \( 9.55 \times 10^{-8} \) in standard (decimal) form, shift the decimal point in \( 9.55 \) eight places to the left because of the negative exponent.
Starting with \( 9.55 \):
- Moving the decimal point 1 place left gives \( 0.955 \)
- Moving it 2 places left gives \( 0.0955 \)
- Moving it 3 places left gives \( 0.00955 \)
- Moving it 4 places left gives \( 0.000955 \)
- Moving it 5 places left gives \( 0.0000955 \)
- Moving it 6 places left gives \( 0.00000955 \)
- Moving it 7 places left gives \( 0.000000955 \)
- Moving it 8 places left gives \( 0.0000000955 \)
So, \( 9.55 \times 10^{-8} \) in standard form is \( 0.0000000955 \).
