What makes up a log?
Just as an exponential function has three parts, a logarithm has three parts as well: a base, an argument and an answer (also called power). In this function, the base is 2, the argument is 3 and the answer is 8.
Where does the log function come from?
Logarithms were invented in the 17th century as a calculation tool by Scottish mathematician John Napier (1550 to 1617), who coined the term from the Greek words for ratio (logos) and number (arithmos).
How does log form work?

Who invented logarithm table?

What are Dura logs made of?
Duraflame firelogs are made of a scientific blend of sawdust, wax, and unique fibers. Some interesting materials tested have included recycled fibers such as nut shells, seeds, fruit pits, distillery grains and recycled cardboard. Natural seed is added to some logs to create crackling sounds of a wood fire.
