Write the expression in exponential form.

log b n = x

Explanation: Recall what the relationship between logarithmic functions and exponential functions are; they are inverses.

In order to convert a log function into an exponent, we need three things: the base, the power, and the answer.

Logs have it in the form: , where b is the base, p is the power, and a is the answer.

Hence, if we want to write it in exponent form, we'd simply turn the tables.
Exponent form:

Hence, for this log function, we'll write:

20 percentage, you can also do it on a calculator.
