Use properties of logarithms to expand the logarithmic expression as much as possible. Consider an examples like subtraction is the inverse of addition and division is the inverse of multiplication. First, the following properties are easy to prove. To check if this is correct, we can evaluate the logarithms, that is: log 2 8 = 3, because 2 3 = 8. log 2 32 = 5, because 2 5 = 32. log 2 256 = 8, because 2 8 = 256. In other words, when a logarithmic equation has the same base on each side, the arguments must be equal. Step 2: Apply Property 3 or 4 to rewrite the logarithm as addition and subtract. In the actual form, it is impossible to find an exact value for the expression, as no integer can be an exponent of 6 to give 24, or an exponent of 6 to give 9. Because logarithms are actually exponents, they have several properties that can be derived from the laws of exponents. Hence, the quotient property of logarithms is already confirmed as true. y = log b x. e y = x. Before getting into the properties of logarithms, lets briefly discuss the relationship between logarithms and exponents. Natural logarithm (ln) rules & properties. log a (m n) = log a m + log a n.
