[tex]\begin{gathered} \frac{6.8\times10^4}{9.3\times10^6}=(\frac{6.8}{9.3})\times10^{4-6} \\ \end{gathered}[/tex]
First we solve the quotient of the numbers and the quotient of exponents separately
[tex]\frac{6.8\times10^4}{9.3\times10^6}=(0.7311)\times10^{-2}[/tex]As the quotient left us a decimal number we can also express it in the form of scientific notation. And so add their exponents to reach the solution
[tex]\begin{gathered} \frac{6.8\times10^4}{9.3\times10^6}=(7.311\times10^{-1})\times10^{-2} \\ \frac{6.8\times10^4}{9.3\times10^6}=7.311\times10^{-1-2} \end{gathered}[/tex][tex]\frac{6.8\times10^4}{9.3\times10^6}=7.311\times10^{-3}[/tex]
