Here log x y is known as the logarithmic form and xz y is known as the exponential form. Sign in with Facebook. Log b x log c x log c b Derivative of logarithm.
Log b x n n log b x Change of base rule.
Using what you now know about the relationship between logarithms and exponential equations break the logarithm apart and rewrite the equation in a simpler solvable exponential form. The logarithm is denoted log b x pronounced as the logarithm of x to base b or the base-b logarithm of x or most commonly the log base b of x. It explains how to convert from logarithmic form to exponen. Solve for x in the equation Ln x8.
