Logarithms - Khan Academy
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.

Module 3: Exponential and logarithmic functions | Khan Academy
They explore (with appropriate tools) the effects of transformations on graphs of exponential and logarithmic functions. They notice that the transformations on a graph of a logarithmic function relate to the logarithmic properties (F-BF.B.3).
