Question

write 0.0000085 in scientific notation.

Explanation:

Step1: Move decimal point

Move the decimal - point to the right until there is only one non - zero digit to the left of the decimal point. For 0.0000085, we move the decimal point 6 places to the right to get 8.5.

Step2: Determine exponent

Since we moved the decimal point 6 places to the right, the exponent of 10 is - 6. In scientific notation, a number is written as \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer.

Answer:

\(8.5\times10^{-6}\)
