How to solve for an exponent with log
Did you know?
WebBy definition, a log a x = x, as log a x is the unique number b such that a b = x. Thus the equation is simply 2 k = 9. I wouldn't use the longer way of writing the equation as 3 log 3 ( 2 k) = 3 2, from which we can infer log 3 ( 2 k) = 2 and therefore 2 k = 9 by definition of logarithm.
