What is the correct way to write 0.00120 in scientific notation?

Answer 1

Scientific notation consists of a number from 1-10, with the multiplication of 10 to the power of (x) for every spot that it takes for the decimal point to make the number 1-10. So to answer your question, 0.00120 in scientific notation would be 1.2 x1000. This is because the decimal point needed to be moved 3 spaces. So 10 times (x), in this 3, creates the formula 10 to the 3rd power. OR just write the number '1' down, and for every spot moved, add a 0. This is much easier (and not to mention FASTER) in my opinion.
