Always remember, you may use the natural logarithm to solve for any base: i.e., for any arbitrary base b, the logarithm of x to the base b is: ln(x)/ln(b)

You can convert a log of x in base a to log of x in base b, divide by the log of a in base b.

This could be better answered on the math site, but is easy enough to just answer here.
