Condensing logarithmic expression into one single expression

The video tutorial explains the process of condensing logarithms, which involves rewriting multiple logarithms as a single logarithm. It contrasts this with expanding logarithms, where a single logarithm is expressed as multiple ones. The tutorial emphasizes that the same rules apply in both processes. An example is provided to illustrate how two logarithms set up as addition can be rewritten by multiplying their products.
