Identify the decimal number given: 0.00015.
To write a number in scientific notation, express it as a product of a number between 1 and 10 and a power of 10.
Move the decimal point in 0.00015 to the right until you have a number between 1 and 10. Count how many places you move the decimal point.
Since you move the decimal point 4 places to the right, the exponent on 10 will be negative 4, because the original number is less than 1.
Write the number as \(1.5 \times 10^{-4}\), which is the correct scientific notation for 0.00015.
