I 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
