log(2^(6x-1))=log9, (assuming your exponent is 6x-1)
(6x-1)log2=log9
6x-1=log9/log2
etc
Unless you use some kind of interpolation, using logs along with a calculator will give you the most accurate answer.
(I got x=.6949875)
2^6x-1 = 9
and...
can you solve exponential functions without using log if the base isn't the same..?
