How to rearrange to solve for an exponential function

[ABR124]

I am having difficulty trying to rearrange this equation to solve for one unknown variable.

i=(io)exp(z*α*F*∆V)/(R*T)

How would I rearrange this equation if i wanted to solve for io, also how would I rearrange this equation to solve for say α.

Solving for i₀ is trivial, your equation is basically
i = i₀ * something
so
i₀ = i / something.

To solve for α is a bit trickier, you can first rewrite it to
(i / i₀)*R*T=exp(z*α*F*∆V),
then take the natural logarithm to get
z*α*F*∆V = ...
and finally solve that for α.
