How do you write 4.5 x 10^11 / 6 x 10^2 using a calculator?

We are given
[tex]\frac{4.5\times10^{11}}{6\times10^2}[/tex]We want to write using a calculator
Solution
We first note that
[tex]10^n=En[/tex]on calculator
Now, we come back to the question
[tex]\begin{gathered} \frac{4.5\times10^{11}}{6\times10^2} \\ \frac{4.5\times E11^{}}{6\times E2^{}} \\ \frac{4.5E11^{}}{6E2^{}} \end{gathered}[/tex]Thus, the answer is (4.5E11)/(6E2)
Option B
