**ln**. In general, ifa>0, a≠1, then the inverse of the function ax is the"logarithm base a", loga(x).

Similarly, you may ask, what does natural log mean?

**Natural Logarithm**. The **natural logarithm**of a number x is the **logarithm** to the base e , where e isthe mathematical constant approximately equal to 2.718 . It isusually written using the shorthand notation lnx , instead of**log**ex as you might expect .

Subsequently, question is, what is a log in math? In **mathematics**, the logarithm is the inversefunction to exponentiation. That means the logarithm of a givennumber x is the exponent to which another fixed number, the base b,must be raised, to produce that number x.

Also, what is ln and log?

Usually **log**(x) means the base 10 logarithm; itcan, also be written as **log**10(x) . **ln**(x) means thebase e logarithm; it can, also be written as **log**e(x) .**ln**(x) tells you what power you must raise e to obtain thenumber x.

What does Ln stand for?

The natural log is the inverse of e , a fancy term foropposite. Speaking of fancy, the Latin name is logarithmusnaturali, giving the abbreviation **ln**. Now **what does**this inverse or opposite stuff mean? ex lets us plug in time andget growth. **ln**(x) ? lets us plug in growth and get the timeit would take.
