2^6x-1 = 9

and...
can you solve exponential functions without using log if the base isn't the same..?
Answered by Reiny
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.

you got 8 hours of sleep on Monday night and 7 hours of sleep on tuesday night. On wednesday, you got 4 hours of sleep because you were up late working on a english paper. On thursday and friday you got 9 hours of sleep each night to make up for wednseday. Use a verbal model to find how many hours of sleep you got during the week?
