Logarithmic function exponential form. On the other hand the logarithmic function is defined as the inverse function of exponentiation. A logarithm is simply an exponent that is written in a special way. This function can be represented in logarithmic form as. Logarithms are really useful in permitting us to work with very large numbers while manipulating numbers of a much more manageable size.

For example we know that the following exponential equation is true. So a log is an exponent. Given an exponential equation in which a common base cannot be found solve for the unknown. B y x if and only if y log b x for all x 0 and 0 b 1.

Examine the equation latex y mathrm log b x latex and identify b y and x. Write log z w t in exponential form. Logarithmic functions are inverses of exponential functions. Use the definition of a logarithmic function to rewrite the equation in exponential form.

Y log b x if and only if b y x for all x 0 and 0 b 1. Logarithmic functions are the inverses of exponential functions and any exponential function can be expressed in logarithmic form. Write log 5 125 3 in exponential form. Exponential to logarithmic form exponential functions are inverses of logarithmic functions.

At this point i can use the relationship to convert the log form of the equation to the corresponding exponential form and then i can solve the result. Given an equation in logarithmic form latex mathrm log b left x right y latex convert it to exponential form. Now the equation is arranged in a useful way. Rewrite latex mathrm log b x y latex as latex b y x latex.

Y log b x. 8 x2 2 x. We can write this equation in logarithm form with identical meaning as follows. Similarly all logarithmic functions can be rewritten in exponential form.
