Explanation:
As I understand the question you have the following expressions given in scientific notation:
Expression A:
[tex]9\times10^2[/tex]
Expression B:
[tex]3\times10^{-2}[/tex]
So we need to compare both expression in order to know how much times is expression A bigger than B. So:
[tex]\frac{9\times 10^2}{3\times 10^{-2}}=\frac{9}{3}\times10^{2-(-2)}=3\times 10^4=30,000 \\ \\ \\ *\frac{a^n}{b^m}=a^{n-m}[/tex]
In conclusion [tex]9\times10^2[/tex] is [tex]30,000[/tex] times as much as [tex]3\times10^{-2}[/tex]
