# Algebra 2 – Common Logarithms

Yay Math In Studio returns for a dive into common logarithms. How common are they? Well, base 10. Hopefully that's common enough for us all. Using logarithms of base 10, we can solve exponential equations using our calculators. We call it "log both sides", which is a great way to solve equations AND inequalities. Using properties of logarithms, we can solve for the variable we're looking for. YAY MATH!
