Question

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

Answer 1

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.

Answer 2

-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
