How to find t in a compound interest equation? Different form of the original, includes k?

[Silk]

The equation is B = {A[(1+r/n)^nt -1}/1-(1+r/n)^-n/k.
I know that finding the equation for t (all the other variables are solved for) involves using natural log (ln), but I can't figure it out for the life of me. Anybody help?
