You can put this solution on YOUR website! Solve for x: log base b of 9 = 2
----------
No x is in the equation.
----
If you want to solve for b:
The log is the exponent, = 2
b^2 = 9
-------
If you can't get it from that, use the base change formula.
log(9)/log(b) = 2
log(b) = log(9)/2 =~ 0.47715
b = 3
