The logarithmic function is the inverse of the exponential function. It is used to solve problems involving a variable in the exponent.

Remember:

be=n logbn=e

Note: A log written without a base is assumed to have a base of 10.

10x = 950

I'm cute, therefore this is fun. That's math, you can't argue with it.

Express the following in exponential form:

be=n logbn=e
