The logarithm function is the reverse of exponentiation and the logarithm of a number or log for short is the number a base must be raised to to get that number. X Divide both sides by 2 to get x by itself. 2 Get the logarithms of both sides of the equation.
Then the logarithmic function is given by.
When you have log b b m the logarithm undoes the exponent and the result is just m. If one of the terms in the equation has base 10 use the common logarithm. Next well use one of the properties of logarithms which allows us to remove an exponent from the argument. Apply the logarithm of both sides of the equation.
