Recasting it slightly (letting 1+i = y) shows that it can be rearranged, but only if you use a numerical-only function (the ProductLog function) .

A friend sent me this and I’m wondering if anyone here can help. I don’t think it’s possible but would appreciate confirmation!
If x = (1 - vn)/ä
where:
v = 1/(1 + i)
and
ä = ln(1 + i)
Is there a way to write a formula for i in terms of n and x?
Edit: just can’t see a way to free the i from the ln without locking the other up with an e…
