anthonyym · Answer

Well first you can compare the 8 and 2, how many times 8 is greater than 2. Then you compare the 10 to the power part and see how many times 10^7 is greater than 10^4 (do 10^7 divided by 10^4).

anthonyym · Answer

Because you're really doing $$\frac{ 8*10^7 }{ 2*10^4 }=\frac{ 8 }{ 2 }*\frac{ 10^7 }{ 10^4 }$$
