WebApr 9, 2024 · By using the rules of exponents, we can solve several exponential equations and rewrite each side with the same base as power. Then we use the fact that exponential functions are individually to compare the exponents and solve the unknown. If an exponential equation with a shared base cannot be rewritten, overcome by using each … 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.
