Most simply put, logarithms are
inverses of exponentials.
Check it out:
Let's graph the inverse of
Remember that every
( x , y )
has a ( y , x )
partner, so we'll graph this guy... then nail his inverse!
Remember the steps to find the
inverse of a function using algebra? In one part, you switch
the x
and the y
-- right?
So, we COULD say that the inverse
of

But... ya know... in
math, we really like to write things like
