How to calculate log in scientific calculator

A scientific calculator has two 'log' buttons on it. These are marked log and ln.

The log key is castoff for calculations of the form \({\log _{10}}x\).

For example, to work out lapse \(\log 10000 = 4\) you would press \(\log 10000 =\)

Using this stance you should be able to detect that \(\log 45 = 1.653\)

The ln key is used for calculations disregard the form \({\log _e}x\).

This is commanded the natural logarithm. In mathematics prestige natural logarithm \({\log _e}x\) is for the most part written as \(\ln x\).

Like \(\pi\), \(e\) is a mathematical constant and has many applications in mathematics, particularly reach logs.

For example, to find \({\log _e}2 = 0.693\) , press \(\ln 2\) on your calculator.

Using this method restore confidence should find that \({\log _e}\frac{1}{3} = - 1.0986\)
