👉 Learn how to evaluate basic logarithms. Recall that the logarithm of a number says 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, we either rewrite the expression as an exponential equation using the definition of a logarithm or evaluate using the properties of logarithms.
