Exponential and Logarithmic Functions Mathematical Practices
Relationship Between Log And Exponential
Convert the outer logarithm into its exponential form. Set the exponential product equal to the inside logarithm. Change the logarithm into its exponential form. Rearrange the exponential equation to isolate 'x'. #Math #Algebra #Equations #Logarithms
Logarithms are basically the inverse function of exponentiation. You need a number (N), a base (a), and the logarithm of N in base a will be x, where N equals a to the power of x. It might seem like only a different way of writing the same thing (and in a sense, it is), but logarithms have a myriad of practical applications, being used in psychology, economy, and measurements of many physical phenomena (such as pH ). Logarithms were publicly propounded by John Napier in 1614
Log Function Vs Exponential Function
