**Reiny**, Sunday, May 5, 2013 at 8:43pmI will assume that your base is 10

log(x^2 + 1) = x/6

x^2 + 1 = 10^(x/6)

There is no easy way to do this, so I will resort to good ol' Wofram, (one of the best math-sites on the net)

http://www.wolframalpha.com/input/?i=solve+x%5E2+%2B+1+%3D+10%5E%28x%2F6%29

as you can see

x = 0

x = .416103

x = 3.6267

I tested all three answers , they all work

I had done this question before for somebody else.

However, in that solution I assumed the base was e

and of course we got 3 different answers
