Like what buttons in my Ti-Nspire do I press. What are the steps.
I'm doing chemical calculations and working on first and second order rates. And I'm stuck in ln[Ao]=-2.30
How do I calculate ln[x]=-2.30

0Okay. Yes. Possibly. I know a little about ln. But hey thanks for being a troll. Feel free never to comment on my question again. – 2017-02-20

0Concentration of a given time but I suppose you can rid of those and it'll be ln(x) = -2.30 – 2017-02-20

0Are you trying to find an explicit solution for $[A_0]$? $$[A_0]=\cdots$$ – 2017-02-20

I don't own a TI Nspire but i used these steps to solve it using calc.exe:
Solve the equation by rewriting in exponential form using the definition of a logarithm, then simplifying you get x=1/(e^(2.3)) = approximately 0.10025884
