@humanityexists There are two ways you could do it: The easier way is by separating the ln(0.691/k) into ln(0.691) - ln (k). Then you can rearrange to find ln (k).
This gives you ln(k) = ln(0.691) - 0.001902.
Then powering both sides by e gives you
k = e ^ (ln(0.691) - 0.001902).
Another way you could have done it is by powering both sides by e to begin with and rearranging to find k. Either way you'll get the same answer :)
@YourSoDom you sure you copied down the question right? This involves solving a 3rd degree poly. The only real soln is x=0.966. If the question was e^(-2x)+e^(-1x)=0.2, you could make the substitution e^x = u solve a quadratic. Which seems a lot more appropriate
thank you!!!

ok so i have this chemisty problem
ln(.691 / k) = .001902
how would I find k?

@humanityexists
you cant
but i can
but i wont tell you
because i secretly dont know how
infact idk how i got to this part of youtube
