Question

Note that there are two possible forms for the third property. Usually which form you use is based upon the form you want the answer to be in.

Note as well that several of these properties were given along only two terms/factors but they can be extended out to as several terms/factors as we required.  For instance, property 4 can be extended as follows.

                                                 (abcd )n  = aⁿbⁿ cⁿ dⁿ
