their is no any answers for it

anonymous · Answer

Haha, I was so confused by the possible answers. The easiest way to do this is to count all the zeros and first nonzero. That will give you what power it goes to. Since it's a decimal, it will be negative. So your power will be -6. The first nonzero is 3 and you have to round up, so it will be 4. Your answer will be$$4\times10^{-6}$$
