## About this unit

You've seen inverse operations like multiplication and division. Because powers are not commutative, it takes two operations to undo them. Radicals let us work backwards to get a base, but logarithms retrieve the exponent. The logarithmic properties may look new, but they're just the exponential properties in a new notation.
