need right side filled out i did the work already

From the given qestion,
In the right side of the given field;
There are given that,
Divide both side by.....
Now,
According to the given solution,
[tex]15=36e^{-0.0000000005545t}[/tex]So,
First field:Divide both side by 36 of the given exponential function.
Now,
Apply the exponential rule;
From the exponential rule;
If,
[tex]\begin{gathered} e^x=a,\text{ then;} \\ x=\ln a \end{gathered}[/tex]So,
In the second field of the given exponential is,
[tex]\begin{gathered} e^{-0.0000000005545t}=\frac{15}{36} \\ e^{-0.0000000005545t}=0.41666 \\ -0.0000000005545t=\ln (0.41666) \end{gathered}[/tex]Then,
Second field:Divide both side by 0.0000000005545 on the above exponential function.
