Explanation:

Step1: Recall scientific notation rules

Scientific notation is in the form \( a \times 10^n \), where \( 1 \leq |a| < 10 \) and \( n \) is an integer. For a number less than 1, we move the decimal point to the right until we get a number between 1 and 10, and \( n \) is negative (equal to the number of places we moved the decimal).
For \( 0.00000001 \), we move the decimal point 8 places to the right to get \( a = 1 \).

Step2: Determine the exponent

Since we moved the decimal 8 places to the right, \( n=-8 \). So the number in scientific notation is \( 1 \times 10^{-8} \).

Answer:

\( 1 \times 10^{-8} \)
