Scientific notation is used by scientists to write very large and very small numbers. Which option correctly represents the scientific notation of 0.000001846?

Move the decimal point to the right until there is only a single digit to the left of it. The decimal has been moved six places from its original location, so the value of the exponent of 10 will be 6. Since the decimal point was moved to the right, the exponent will be negative, which gives the final answer of \(1.846 \times 10^{-6}\).
