Exponential form to logarithmic form calculator

When an exponential equation cannot be rewritten with a common base, solve by taking the logarithm of each side. See Example \(\PageIndex{5}\). We can solve exponential equations with base \(e\),by applying the natural logarithm of both sides because exponential and logarithmic functions are inverses of each other.

The formula y = logb x is said to be written in logarithmic form and x = by is said to be written in exponential form. In working with these problems it is most important to remember that y = logb x and x = by are equivalent statements. Example 1 : If log4 x = 2 then x = 42 x = 16 Example 2 : We have 25 = 52.
