For example, you can calculate log base 3 of 5 by calculating (ln 5)/ (ln 3) which should give approximately … WebJun 10, 2016 · Your first step is to remember that a y = b is the same thing as log a b = y. For your problem, let a = 2. Then b = 7 2x and y = x - 6. So you have log 2 (7 2x) = x - 6. That may look equally daunting, but here you can make use of the rule that tells you log a (b x ) = xlog a b. In your case, this means we have 2x (log 2 7) = x - 6.
