Pre-Calculus - Evaluating the Difference of Two Logarithms

👉 Learn how to evaluate logarithm expression. Recall that the logarithm of a number say a to the base of another number say b is a number say n which when raised as a power of b gives a. (i.e. log [base b] (a) = n means that b^n = a). Thus, to evaluate logarithms expressions, we either rewrite the expression as an exponential equation using the definition of a logarithm or evaluate using properties of logarithms.

When the logarithm expressions involve the addition or subtraction of individual logarithms of the same base, we can use the addition or the subtraction laws of logarithms to evaluate the value of the logarithm. Otherwise, we can make use of other logarithm properties to evaluate the logarithm expression.
