What is the power of 10 when 0.000028 is written in scientific notation

Scientific notation is the way that scientists easily handle very large numbers or very small numbers.

For example, instead of writing 0.0000000056, we write
5.6 * 10^(-9).

Hence, in scientific notation

0.000028 =
2.8 * 10^(-5)

So, the answer is -5. The power of ten has to be -5.

-5 as that you would have to count that places to the left. You end decimal would have to be between 1 and 10, so it would not count the 8. I'm sorry if my explanation is not good, but that is the right answer
