Solve for Intensity: Easy Formula Manipulation for Finding Intensity

I'm trying to find the intensity of something. I know the equation is

B = 10log(I/Io)

But how to I solve for I? What would the equation be? For some reason I can't make it work.

Does this help?
If [tex]a = log(b)[/tex]

then [tex]b = 10^a[/tex]
 
No, i still can't ge thte correct equation, i come up with something like (10x10^B)/Io
 
Rewrite the equation as
I/I0 = 10^(B/10)

Not quite:
B = 10log(I/Io)
B/10 = log(I/Io)
10^(B/10) = I/Io
I = Io*10^(B/10)
 
Thanks, that is kinda tricky, but now i understand it
 
From the provided information, Doc Al's equation is correct. You may be using wrong values for your Io and B, or your intensity equation could be incorrect.
