Given:
[tex]\frac{6.6\times10^8}{2.0\times10^4}[/tex]Simplify the expression
[tex]\frac{6.6\times10^8}{2.0\times10^4}=\frac{6.6}{2.0}\times\frac{10^8}{10^4}[/tex]Solve the expression by applying the law of indices
[tex]\frac{6.6\times10^8}{2.0\times10^4}=\frac{6.6}{2.0}\times10^{8-4}[/tex]Simplify further
[tex]\begin{gathered} \frac{6.6\times10^8}{2.0\times10^4}=3.3\times10^{8-4} \\ \frac{6.6\times10^8}{2.0\times10^4}=3.3\times10^4 \end{gathered}[/tex]Therefore, the answer is
[tex]3.3\times10^4[/tex]
