How do I calculate ln[x]=-2.30

Question

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

Answer 1

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
