Say that a proton has a size of 0.000000000123 and an electron has a size of 1.4x10^-8. How many times smaller is an electron than a proton?
Now I have to change the size of the proton into scientific notation. When I did this I got 1.23x10^-10. Is my answer correct? If not could you tell me how to get the correct answer. Thank you.
