does ln x e x Is it possible to prove e ln x x for a student or can you only say that exponentiation is defined to be the inverse of natural logarithm and stop there
Why does e ln x equal to x Proof Start the proof by letting y e ln x and applying the natural log to both sides By following standard logarithmic rul The equivalent rule of ln is e ln x x Product Rule of Logarithms By the product rule of logarithms the log of a product of two terms is equal to the sum of logs of individual terms i e the rule says log b mn log b m log b n

That is ln e x x where e x is the exponential function The natural logarithm function is defined by ln x Integral on the interval 1 x of 1 x d t t for x 0 therefore the derivative of the natural logarithm is d d x ln x For all y 0 lny is by definition the power that e must be raised by to give the value y So elny y In particular it is true for any x such that xx 0 So substituting xx for y elnxx
Like most functions you are likely to come across the exponential has an inverse function which is log e x often written ln x pronounced log x In the diagram e x is the red line lnx the green line and y x is the yellow line Ln x Natural Logarithm is the time to reach amount x assuming we grew continuously from 1 0 Not too bad right While the mathematicians scramble to give you the long technical
