Best ResponseYou've already chosen the best response.0you already have masses written in scientific notation. So you just need to solve \[4.55*10^{13}  1.78*10^{12}\]

Best ResponseYou've already chosen the best response.0you can do this way: \[4.55∗10^{13}−1.78∗10^{12}=10^{12}*(4.55*101.78)\] then solve for the number in brackets

Best ResponseYou've already chosen the best response.0in brackets you get 43.72. But the a must be less than 10, so the answer will be \[4.372*10^{12}*10=4.372*10^{13}\]
