How to solve for an exponent with log

WebUse the following steps to solve exponential equations using the natural logarithm function. Take the natural logarithm of both sides of the equation. Use the power rule of logarithms to remove ... 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.
