Logarithms are ways to figure out what exponents you need to multiply into a specific number For example using the Log function on the number 10 would reveal that you have to multiply your base number of 10 by itself one time to equal the number 10 A scientific calculator has two log buttons on it These are marked log and ln The log key is used for calculations of the form log 10 x For example to work out that

A logarithmic function is an inverse of the exponential function In essence if a raised to power y gives x then the logarithm of x with base a is equal to y In the form of equations a x is equivalent to log x y In other words the logarithm of x or log x shows what power we need to raise a to or if x is greater than 1 how many times a Logarithms are a means of calculating how many exponents you ll need to multiply a given integer For example applying the Log function on the number 10 reveals that to equal the number 10 you must multiply your base number of 10 by itself once On your calculator press the Log button
In mathematics the logarithm is the inverse function to exponentiation That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x For example since 1000 103 the logarithm base 10 A scientific calculator generally always has an ln natural logarithm or log base e key From the change of base theorem log base a of b ln b ln a For example you can calculate log base 3 of 5 by calculating ln 5 ln 3

Step 1 Enter the Number Turn your calculator on and type in the number you want to calculate the common logarithm log base 10 of Let s use 1000 as an example Step 2 Press the Log Button To apply the log function on the number click on the log button on the calculator If you have a graphing calculator like this you literally can literally type in the statement natural log of 67 then evaluate it So here this is the button for ln means natural log log natural maybe ln of 67 and then you press Enter and it ll give you the answer
Now that you know how to use log and antilog tables let us perform some calculations using logs Example 1 Use logs to evaluate N frac 647 cdot 32 times 0 00000147 8 473 times 64 Solution Our approach consists of four steps convert the expression for N into logs evaluate those logs using a log table 11 years ago Logarithm is based on the combination of two Greek words logos and arithmos number Logos is a rather curious Greek word with multiple meanings In this case you could translate it as ratio or proportion The word logarithm was invented by John Napier in 1614
