Answer :
[tex]\frac{4.68\times10^6}{2.6\times10^2}[/tex]
To solve the quotient between 2 numbers in scientific notation we have to perform 2 operations, one with the exponents of the notation and another between the numbers in the following way
[tex]\begin{gathered} \frac{4.68\times10^6}{2.6\times10^2}=\frac{4.68}{2.6}\times10^{6-2} \\ \frac{4.68\times10^6}{2.6\times10^2}=1.8\times10^4 \end{gathered}[/tex]So the answer is
[tex]1.8\times10^4=18000[/tex]
