In this video, we use the Change of Base Formula to evaluate log₃14 step by step 📘. When a logarithm has a base that isn’t available on your calculator, the change of base formula lets you rewrite it using common log or natural log.

We apply the formula log_b(a) = log(a) / log(b) to rewrite log₃14 as log(14) / log(3), then evaluate it using a calculator. You’ll see exactly why the formula works and how to use it confidently on tests and homework.

This is a key Algebra 2 skill and shows up often when solving exponential and logarithmic equations that don’t simplify nicely.
